Three groups of 13 adult female rats received daily for two months 23 g per rat of three synthetic isoenergetic feeds containing respectively 5, 15, 25 p. 100 casein. Plasma urea was measured weekly. Hair leachable urea and soluble dry matter were measured, at the end of the experiment, on hairs regrown after an initial clipping, in a solution obtained by washing 1 g of hair in 50 ml of HCl 0,01 N under mechanical shaking. Mean plasma urea values for the whole experiment for the three groups were 0.27, 0.38, 0.45 g per liter; differences between all groups were highly significant; however differences for the 15 and 25 p. 100 casein groups were not significant for the last three weeks. Hair leachable urea and hair soluble dry matter values were respectively 0.35, 0.80, 1.02 mg/g of hair and 20.4, 24.0, 26.0 mg/g of hair. A positive correlation links hair urea to hair dry matter (r=0.76, p less than 0.001). When hair urea is expressed in per cent of soluble dry matter, the respective values for the three groups are 1.90, 3.42, 3.95. Differences between the 5 p. 100 casein group on the one hand and the 15 and 25 p. 100 casein groups on the other are highly significant (p less than 0.001).

We report a 41-year-old male of citrullinemia associated with argininosuccinate acid synthetase deficiency. He was admitted to the Hitachi General Hospital because of finger tremor, restlessness and urinary incontinence. He had short stature and a poor appetite. Laboratory evaluation was summarized as follows: mild hypoglycemia, low plasma cortisol levels, delayed response of 17-OHCS and 17-KS to ACTH administration in urine, and delayed response of plasma ACTH level to insulin administration. In this case, ACTH deficiency is estimated to be a dysfunction of the hypothalamus. Replacement therapy of hydrocortisone improved his symptoms. He was readmitted to the hospital because of delirium and confusion, two weeks after the hydrocortisone administration. At that time, he had flapping tremor. Laboratory examination revealed hyperammonemia (NH3: 231 micrograms/dl) and mild elevation of GOT and GPT. Serum and urinary amino acid determination showed marked elevation of citrulline (478.1 nmol/ml in serum, 4681.2 mumol/day in urine). Lactulose administration, low protein diet and plasmapheresis were started, but he went into a coma. Without any improvement, he died on the 29th hospital day. Autopsy examination of the liver disclosed fatty change. Adrenal cortex depicted severe atrophy. Biochemical analysis of urea cycle enzymes of the liver and kidney showed decreased activity of argininosuccinate synthetase (liver: 0.0022 U/mg protein, 5% of that normal liver, kidney: 0.003 IU/mg protein, 20% of that in normal kidney). Citrullinemia associated with ACTH deficiency have not reported in the literature. It may be presumed that ACTH deficiency is concerned with the delayed onset of hyperammonemia. The relation between citrullinemia and endocrinological abnormalities is also discussed.

Adult sows fed a constant amount of a basal diet received purified cellulose either orally at levels of 0 and 475 g/animal.d (Experiment 1) or intracecally at levels of 0, 285, 570 and 855 g/animal.d (Experiment 2). Each experiment consisted of subsequent periods of faeces and urine collection with the animals re-allocated to the treatments each time. With that, a total of 36 observations on each parameter was achieved. The faecal samples were analyzed for the contents of organic matter, cell wall carbohydrates and various nitrogen fractions such as bacterial N and undigested dietary N. Furthermore, N balance, urinary allantoin excretion and plasma urea concentrations were determined. In a preliminary study, the effects of freeze-drying and of shaking of the faecal samples as suspensions with water (in order to release bacteria from fibre) on content and composition of faecal nitrogen had turned out to be reproducible. Cellulose significantly enhanced faecal nitrogen loss whereas N retention was not affected due to the counteraction of urinary N loss. Plasma urea concentration reflected the situation with urinary N. The proportion of undigested dietary N and of water-soluble protein in total faecal N was somewhat increased by cellulose at cost of the bacterial N proportion which accounted for about 72% of total N on average. Urinary allantoin did not respond to the higher bacterial activity in the hindgut in the presence of supplementary cellulose. Cellulose significantly decreased the apparent N digestibility by on average about 3 percentage units per 100 g of supplementary cellulose. True N digestibility was also reduced by cellulose but did not go below 95%. The supplementary cellulose was fermented in the hindgut at similar rates of on average about 60% regardless of the route of administration. The almost 100 g of native cellulose incorporated in the basal diets were lignified by about 20%, and that is why they were fermented at a rate of only about 30%. The rate of fermentation was only slightly decreasing with increasing amounts of supplementary cellulose, and a daily quantity of 564 g (11 g/W0.75) cellulose was fermented on average if the highest level of cellulose was provided. This was within a range exclusively reported for easily-fermentable carbohydrates but was achieved in the case of cellulose only at a consistently higher level of supply. The true efficiency of bacterial protein synthesis was 5.2 g bacterial protein/100 g supplementary cellulose on average. The apparent efficiency was 60% higher averaging 8.4 g bacterial protein/100 g further apparently fermented organic matter.

A new technique, checkerboard immunoblotting (CBIB), has been applied to detect and to differentiate heat-labile enterotoxins, (LTs), from enterotoxigenic strains of Escherichia coli of human origin using polyclonal and monoclonal antibodies. Optimal conditions of production and release of LTs were defined using CBIB. LT release was enhanced when E. coli cells were treated with 8 M urea. LT production was highest when E. coli strains were incubated with shaking (200 rpm) at 37 degrees C for 12 h in CAYE-2 medium. Two hundred and five strains of E. coli, isolated from patients with diarrhea in Japan, Thailand, the United States, Mexico, and Brazil, were examined for LT. Of 133 LT-positive strains, 4 (3%) produced an LT that reacted like H-LT-1 (originally isolated from E. coli strain H-74-114) while 126 strains (94.7%) produced LT that reacted like H-LT-2 (originally isolated from strain H-10407) or H-LT-3 (from strain H-240-3). Three strains of human origin (2.3%) produced an LT that reacted like P-LT (produced by E. coli strains of porcine origin). This study shows that CBIB, a simple, efficient, and practical assay, might be useful for epidemiologic surveys and for evaluation of serologic responses to LTs and antitoxic vaccines.

The incidence and significance of elevated serum levels of creatine phosphokinase (CPK) in febrile diseases were studied prospectively in all patients admitted with fever to a department of medicine during 1 year. High serum CPK levels were detected in 70 (28%) of 247 febrile patients but in only six (6%) of 105 afebrile control patients (P = .0001). Elevated CPK levels were not related to any specific diagnosis. Logistic regression analysis identified five factors that correlated both significantly and independently with elevation of CPK values: increased blood urea nitrogen level, low serum phosphate level, a stuporous or comatose state, tremor, and muscle tenderness. Myoglobinuria, detected in 14 patients, was predictive of a fatal outcome, but a high CPK level by itself was not an independent correlate of mortality. In summary, CPK elevation is not uncommon in febrile diseases, but because it does not reflect a specific etiology it does not necessarily indicate that an extensive diagnostic work-up is required.

To determine the role played by stagnant peritoneal fluid layers in the diffusion of solutes between peritoneal cavity and blood, we measured peritoneal transfer of urea, creatinine, [14C]-L-glucose and protein in anesthetized rats shaken at varying rates on an orbital platform shaker. The diffusion transfer rates of the low molecular weight solutes increased dramatically with shaking, with near maximal values obtained at a shaking rate of 250 RPM. The permeability area product (PA) for each of the low molecular weight solutes increased about fourfold with rapid shaking while the PA of protein increased by only about 50%. It seems likely while the PA of protein increased by only about 50%. It seems likely that shaking increased PA primarily via reduction of the thickness of stagnant peritoneal fluid layers, although increases in surface area or changes in tissue permeability cannot be excluded with certainty. We conclude that stagnant fluid layers probably are the rate limiting step in diffusive peritoneal transfer of low molecular weight solutes in stationary rats.

A 44-year-old man suffered from repeated impairment of consciousness associated with flapping tremor, myoclonus and generalized convulsions, and died in coma 6 months after admission. He had had a psychosomatically underdeveloped childhood, with a propensity for legumes without a family history of the same or a record of consanguinity. On admission, he had disturbed consciousness and emaciation without other physical abnormalities. The EEG revealed diffuse slow waves with occasional appearance of triphasic waves. A high level of serum citrulline (534.7 nmol/ml) was recognized and the assay of urea cycle enzymes in the liver demonstrated decreased argininosuccinate synthetase (ASS) activity (0.062 U/g liver, 7.4% of that in normal liver), although no kinetic abnormality was found. Accordingly he was diagnosed as having type II citrullinemia. In addition, this case could be classified as cluster type of localization of the ASS in the liver by immunohistochemical study. There were characteristic findings concerning his clinical picture and laboratory data, such as a significant correlation between the grade of disturbed consciousness and arterial blood gas pH (r = 0.61, p less than 0.01). However, the blood ammonia level did not always correlate with the severity of disturbed consciousness. Oral treatment with sodium citrate and sodium benzoate was very effective, though transiently, for disturbed consciousness in this case. Pathological findings of the autopsied liver were fatty change and fibrosis. Neuropathologically, characteristic findings were brain edema with cerebellar tonsilar herniation, laminar necrosis with spongy formation in cerebral cortex, and Alzheimer type II glia. The relationship between citrullinemia and other hepatic encephalopathy was also discussed.

Ciprofloxacin is a new quinolone antimicrobial agent with activity against a broad spectrum of gram-negative and gram-positive organisms, including Pseudomonas aeruginosa and methicillin-resistant strains of staphylococci. The efficacy and safety results of 80 clinical studies of the oral form of ciprofloxacin are reported. Drug safety was assessed in 2236 courses in 2203 adult patients treated primarily in the United States. Data from 1676 courses were suitable for analysis of drug efficacy. The unit dose for most patients ranged from 250 mg to 750 mg (median, 500 mg), usually given every 12 hours. The duration of treatment ranged from 3 to 231 days (median, 10 days). Predominant among 1722 infections were those of the urinary tract (43%), skin structures (29%), and respiratory tract (19%); the remainder were bone and joint infections (5%), bacteremias (2%), and intra-abdominal (1%), gastrointestinal (1%), and pelvic infections (less than 1%). Signs and symptoms of infection resolved in 79% of all cases; a further 15% improved, and 5% failed to improve. Pathogens were eradicated in 89% of urinary tract infections and persisted in 5%; 80% of patients still had sterile urine at the 3-to 6-week follow-up. In 81% of nonurinary tract infections, pathogens were eradicated; they persisted in 11%, and superinfection occurred in less than 5%. After treatment, 89% of the 2253 causative organisms were eradicated and 2% were reduced to clinically insignificant counts; 8% persisted. Of 411 isolates of P. aeruginosa, 77% were eradicated, as were 97% of 421 Escherichia coli and 80% of 248 Staphylococcus aureus isolates. Also eradicated were 95% of 166 Klebsiella, 96% of 139 Proteus mirabilis, 100% of 20 other Proteus, 94% of 123 Enterobacter, 100% of 68 Haemophilus influenzae, 96% of 49 Citrobacter, 89% of 45 Serratia, 95% of 41 Streptococcus pneumoniae, 91% of 43 Salmonella, 100% of 38 Morganella morganii, and 100% of 35 Providencia isolates. Adverse reactions were judged probably or possibly drug-related in 14.8% of courses; drug treatment had to be stopped prematurely in 3.5%. The most frequent reactions were gastrointestinal complaints (chiefly nausea, diarrhea, and vomiting), metabolic disorders (elevated SGOT, SGPT, serum creatinine, or blood urea nitrogen), and nervous system effects (dizziness, light-headedness, restlessness, tremor, and headache). Crystalluria, judged to be related to ciprofloxacin, occurred in two patients.(ABSTRACT TRUNCATED AT 400 WORDS)

The effects of eluent composition, pH, and chaotropic agents on the recovery of T2, MS2, and indigenous coliphages from various foods were investigated. Additionally, methods of sample suspension and clarification were evaluated for coliphage recovery and application to various foods. Clarified sample suspensions were assayed for coliphages with a modified agar layer technique and appropriate Escherichia coli hosts. Centrifugation and polypropylene mesh filtration were more rapid and effective than glass wool filtration for clarification of sample suspensions and subsequent recovery of coliphages. Blending, stomaching, and shaking procedures were generally comparable for sample liquefaction and release of coliphages from foods. Complex basal eluents, EC medium and 1% casein, were generally more effective than a less complex eluent, phosphate buffer, for elution of coliphages from foods. For most foods, incorporation of sodium chloride or chaotropic agents, i.e., sodium trichloroacetate, urea, Tween 80, Triton X-100, and sodium nitrate, into basal eluents did not enhance recovery of coliphages. Indigenous coliphage recovery was not affected by sample suspension pH over a range of 6.0 to 9.0. With an optimal procedure, i.e., EC medium eluent, blending, and centrifugation, the recovery of T2 and MS2 ranged from 48 to 81% and from 58 to 100%, respectively, depending on the food type.

Dementia--a syndrome of acquired intellectual deterioration--is an etiologically non-specific condition which is permanent, progressive, or reversible. In the evaluation of demented patients, a careful exposure history will determine the possible role of drugs, metals, or toxins. The physical examination may reveal focal deficits in cases of intracranial mass lesions and spasticity or ataxia of the lower limbs if hydrocephalus is present. Coexistance of dementia and peripheral neuropathy usually indicates a toxic or metabolic disorder. Asterixis, myoclonus, and postural tremor are common in toxic-metabolic dementias, while resting tremor, choreoathetosis, and rigidity occur in progressive extrapyramidal disorders. EEG is focally abnormal in cases of cerebral mass lesions and exhibits generalized slowing in toxic-metabolic encephalopathies. CT will aid in the identification of hydrocephalus, subdural hematomas, and intracranial mass lesions. A thorough laboratory evaluation including complete blood count, erythrocyte sedimentation rate, electrolytes, blood urea nitrogen and blood sugar, liver and thyroid tests, calcium and phosphorus levels, B12 and folate levels, serum copper and ceruloplasmin, VDRL, chest X-ray, electrocardiogram, and lumbar puncture may demonstrate treatable disorders that are adversely affecting intellectual function. Elderly individuals are particularly susceptible to the effects of toxic or metabolic disorders, and a mild dementia might be exaggerated by relatively minor fluctuations in metabolic status. Treatable causes of dementia should be considered in all demented patients.
