Labrador Retriever puppies (3 kg) were fed L-amino acid (L-AA) diets, containing the equivalent of 14% protein, to determine dietary argnine requirements for optimal growth and maintenance of normal intermediary metabolism. Growth and food consumption were depressed by decreasing the dietary arginine concentration. Urinary citrate and orotate increased with decreasing dietary arginine. Elevated blood orotate, urea and NH4+-N were detected in arginine deficient dogs. More than 0.56% arginine was required to support optimum growth and prevent abnormal loss of urinary metabolites. The effect of dietary nitrogen concentration (14, 21, or 28% L-AA) on arginine requirements was examined in immature Beagles. All arginine deficient dogs and dogs fed the 28% L-AA with arginine showed signs of emesis, excessive salivation and muscle tremors. Hyperammonemia and hyperglycemia were observed 2 hours after force feeding an L-AA diet devoid of arginine. Only hyperammonemia was observed in the Labrador Retrievers fed the same diet but incorporated into a 2% agar gel. Dietary nitrogen concentration or dietary arginine content dit not significantly influence glucose tolerance response to oral glucose loading. These data show that dietary arginine is required in the immature dog and that the requirement is influenced by dietary nitrogen concentration.

In 4 out of 9711 (= 1:2400) patients, lactice acidosis due to biguanides was diagnosed. Serum lactate concentration averaged 18.2 mmol/l and the pH value 6.87. All patients showed signs of renal insufficiency and three had congestive heart disease. In addition to treatment with biguanides, other factors might have contributed to the lactice acidosis in these patients: prolonged fasting, severe dehydration due to persistent vomiting, acute bronchopneumonia, and acute pyelonephritis. On addmission, two patients were in shock and all patients were semi-conscious or comatose. All patients were treated with bicarbonate and glucose/insulin. One patient was hemodialysed. Two of our four patients died. Oour four patients are compared with 179 patients in the literature with respect to mortality and prognosis of lactic acidosis due to biguanides.

The results of 102 cases treated with an oral electrolyte-glucose solution for rehydration caused by mild cases of small bowel diarrhea without using an antimicrobial agent in conjunction are presented. Clinical features, such as frequency of loose bowel movement, age distributions, and other relevant symptomatology are provided tabularly. The solution used consisted of: sodium chloride, .85 gm; potassium bicarbonate, 1 gm.; glucose, 17.5 gm.; boiled and cooled water, 500 ml. 97 of 102 were treated only with the oral electrolyte-glucose solution, and the remainder received intravenous fluid before initiation of oral rehydration. Due to follow-up problems, 13 cases were omitted from the statistical analysis; of the remaining 89, 84 were controlled within 72 hours (as judged by cessation of loose bowel movements). During therapy, breastfeeding or cow's milk was expressly forbidden, but 4 of the 5 failures were later discovered to have recieved breastfeedings, and 1 was marasmic. The treatment of small diarrhea, not having persistent vomiting or shock, with some suitable oral electrolyte-glucose solution only is highly successful, safe, and inexpensive. Success rate was 94.38%.

Infants and young children are particularly susceptible to a recently identified viral enteritis which is highly contagious and seems both common and universal. In this disease, virus invades the upper intestinal epithelium, causing acute diarrhoea with early fever and vomiting. We studied a similar disease in pigs, infecting three-week-old animals with transmissible gastroenteritis virus (TGE), which also invades the upper intestinal epithelium. In this model, diarrhoea is massive 16-40 hours after infection, when stools contain increased electrolytes but no excess of sugar. In the jejunum of intact pigs at the 40-hour stage we found altered Na+ and water flux, decreased mucosal activities of disaccharidases and Na+, K+-ATPase, but normal adenylate cyclase activity. At the same stage the response of Na+ flux to glucose was blunted in jejunal epithelium studied in Ussing short-circuit chambers and in suspensions of villous cells; Cl- flux responded normally to theophylline, and thymidine kinase and sucrase activities of cells isolated from jejunal villi were similar to those found in crypt cells. Probably by 40 hours after infection most virus has been shed from the mucosa. Viral diarrhoea clearly differs from enterotoxigenic diarrhoea. Consideration of its pathogenesis must take into account the dynamic nature of the mucosal epithelium and the factors governing differentiation of enterocytes as they migrate from crypt to villus. Sufficient information is available now to characterize one specific and apparently prevalent viral enteritis in man and to identify additional viral enteritides. There is hope that preventative therapy can be developed. Our understanding of the mechanisms of viral diarrhoea is limited, but the availability of an animal model and the promise of others makes us optimistic that these deficiencies can be remedied. Greater understanding of the pathogenesis of viral diarrhoea should better the active therapy of affected infants and children.

Ten adolescent and young adults with cystic fibrosis (CF) have had well-documented recurrent attacks of acute pancreatitis. The diagnosis of CF in each patient was delayed because they did not have pancreatic insufficiency. The diagnosis of CF was documented by the typical pulmonary involvement and elevated sweat sodium and chloride levels in all cases and a positive family history in six of the ten patients. Two patients were diagnosed as having acute pancreatitis before the diagnosis of CF was made, thus indicating that acute pancreatitis may be the presenting complaint in the young adult with CF. The diagnosis of acute pancreatitis was based on the presence of severe abdominal pain, usually with vomiting, tenderness in the mid-epigastrium, elevated serum and urinary amylase and serum lipase. Attacks were precipitated by fatty meals, alcohol ingestion; postcholecystectomy and tetracycline administration. In some patients no precipitating event could be elicited. Intravenous secretin-pancreozymin stimulation tests revealed a diminished bicarbonate secretion with little effect on the secretion of the zymogen enzymes. A mild attack of pancreatitis occurred after secretin-pancreozymin stimulation. The endocrine pancreatic function tested in four patients was normal as revealed by the glucose tolerance tests and determinations of serum insulin, growth hormone and free fatty acid. Transduodenal pancreatograms were performed in three patients; one showed a normal pancreatic duct, one showed duct obstruction and in the third patient a beady type of narrowing was found. The selenomethionine Se 75 uptake of the pancreas was noted only in the head of the pancreas. This suggests that loss of function occurs initially to a greater extent in the tail and body of the pancreas. Three patients died and showed characteristic lesions of CF.

Four men and 4 women with active acromegaly were treated with bromocryptine for 4 to 5 weeks. Serum growth hormone levels response to a glucose load were measured before and in the last weed of treatment. In only 1 patient was the grwotoh hormone response rendered normal by the drug. This patient, but none of the others, also showed an improvement in glucose tolerance and a reductin of the raised serum insulin levels during the glucose load. In three of the 8 patients vomiting was troublesome side effect of treatment.

Kwashkorkor is associated with malabsorption of energy and nutrients. Standard diets often initiate diarrhea and a high mortality is still prevalent. A synthetic monomolecular formula has been evaluated and compared with a standard diet in the early rehabilitation phase of 21 children with kwashiorkor. The formula group had significantly less vomiting and reached minimum weight faster than the group on standard diet. Weight gain and diarrhea were similar. The rise of albumin and BUN was faster on standard diet. A significant increase in haemoglobin was seen only in the formula group. A rise in body temperature after a meal was evident in most patients and significantly more pronounced in the formula group. The lower total nitrogen content of the formula may explain the observed slower rise in albumin and BUN but the ready utilization was indicated by the favourable weight changes as well as the rise in rectal temperature. As high energy per volume was desirable the formula was not diluted to isoosmolality. However, the high glucose concentration in the experimental diet probably caused some negative effects.

In seven patients with chronic renal failure in an advanced stage 17 episodes of upper abdominal pain, hypertension, vomiting and (in some of them) coma occurred during peritoneal dialysis with sorbitol-containing dialysate. The signs recurred in some of the patients but did not when glucose-containing dialysate of otherwise identical composition was used. Very high levels of sorbitol in CSF and serum were measured in the comatose patients. The precipitating factor is probably a reduced metabolic breakdown of sorbitol in renal failure with preferential intracellular deposition of sorbitol and subsequent cellular oedema. To avoid this dangerous reaction it is necessary to use glucose instead of sorbitol in peritoneal dialysates, despite the technical problems of sterilisation. Where this is not possible, glucose should be added in order to reduce the sorbitol concentration in the dialysate to less than 15g/l.

1. History is unreliable in assessing maternal drug habit. Morphine was detected in significant amounts in maternal and fetal urine regardless of whether the mother was on a methadone program or whether she denied any use of heroin during the last trimester of pregnancy. 2. Infants born to drug-addicted mothers were, in general, of birthweight normal and appropriate for gestational age (i.e., greater that 10th percentile). The infants born to mothers on a methadone clinic program had a higher birthweight compared to those whose mothers were not on any methadone program. 3. In order of frequency, the signs and symptoms of withdrawal were: central nervous system manifestations-fist sucking, irritability, tremors, sneezing, high-pitch cry, hypertonia; vasomotor in the form of stuffy nose; and gastrointestinal in the form of sweating, diarrhea, vomiting and yawning. Convulsions were not noted. No death occurred. 4. The severity of neonatal narcotic withdrawal did not correlate with the infant's gestational age, APGAR, sex or race; nor with maternal age, parity, duration of heroin addiction or duration of methadone intake. Also, it did not correlate with the total morphine level measured either in infant's or mother's urine or in cord blood. The serum levels of calcium and glucose were normal and identical in either mild or severe withdrawal. 5. The severity of neonatal withdrawal correlated significantly with the methadone dose per day of the mother (in initial, final or average dose). A maternal methadone dose of more than 20 mg per day was associated with a higher incidence of moderate to severe withdrawal in their babies. As a corollary, it was also noted that infants whose mothers were on a high methadone dose (i.e., greater than 20 mg per day) had a greater postnatal weight loss despite a significantly higher birthweight initially, and stayed in the hospital longer. 6. Finally, the modification of the environment to reduce external stimuli to the infant born to a drug-dependent mother, does not prevent or diminish the severity of neonatal narcotic withdrawal. Thus, there is no need to manage these infants in a special nursery.

Prostaglandins are a group of modified hydroxy fatty acids with a wide distribution in mammalian tissues. They possess a wide range of potent biological activities and promise to be useful clinically in areas as diverse as the treatment of asthma and termination of pregnancy, in spite of the voluminous scientific literature on prostaglandins, there is little information on the relative safety on these agents in animals. In the present study subacute effects of prostaglandin E1 (PGE1), a representative of the series, were studied in albino rats and Bealge dogs. The compound was dissolved in phosphate buffer and administered by continuous intravenous infusion for 3-6 hr daily, at dose levels up to 2.0 mug/kg/min for 14 consecutive days. Conventional physical, cardiovascular, hematologic, clinical chemical, and postmortem examinations were performed. Dogs exhibited occasional episodes of stupor and/or excitement and emesis. In rats no compound-related physical signs were observed. Cardiovascular parameters and hematology findings were unremarkable. A decrease in blood glucose was observed sporadically in both rats and dogs. Postmortem findings, gross and microscopic, were unremarkable. It is concluded that daily iv infusion of PGE1 up to 2.0 mug/kg/min for 14 consecutive days to rats and dogs causes no biologically meaningful detrimental effects.
