Therapeutic effects of cefprozil (CFPZ, BMY-28100), a new cephalosporin, were examined in various infectious diseases in children. Clinical efficacy rates were 50% (2/4) in acute bronchitis, 80% (4/5) in pharyngitis, 0% in laryngitis, 100% (7/7) in tonsillitis, 100% (8/8) in impetigo contagiosa, furuncle and posthitis. Hence, the overall efficacy rate was 84% (21/25). Adverse effects were observed in 1 case with slightly elevated serum GOT and GPT. Changes in serum concentrations and urinary excretion of CFPZ were examined in 4 and 2 children without infection, respectively. T 1/2 values obtained were between 1 hour to 2 hours (bioassay). Six hour recovery rates in urine were 51.8% and 77.8% (bioassay). CFPZ was considered to be a safe and useful drug in treating various infectious diseases in children.

The case of a two-year-old girl with generalized histiocytosis, probably induced by phenobarbital, is reported. Symptoms, including intermittent fever, systemic lymphadenopathy, maculopapular skin eruption and hepatosplenomegaly, suggested Langerhans cell histiocytosis. Laboratory examinations revealed leukocytosis with lymphocytosis and eosinophilia and a high LDH serum level, while GOT and GPT were within normal ranges. Cytological studies of lymph node and pleural effusion specimens revealed proliferation and infiltration of Langerhans cell histiocytes with eosinophilia. No histiocyte proliferation was observed in the bone marrow or skin. The clinical manifestations shown by the patient were, however, transient, and improved spontaneously after the discontinuation of phenobarbital. The case was considered to be one of phenobarbital hypersensitivity syndrome based on clinical course and laboratory findings. The mechanism and differential diagnosis of the syndrome are discussed.

It has been suggested that depletion of donor hepatic glycogen reserves deleteriously affects the resistance of the hepatic graft to ischemic episodes. In this study, performed in the pig model, we showed that it is possible to enhance the quality of the graft at the time of reperfusion by using a method which rapidly restores the donor hepatic glycogen reserves. With the aid of an isolated liver perfusion model, we compared grafts (n = 24) harvested from pigs fed (group N), fasted for 24h (group J), or fasted with a restoration of glycogen reserves (group P). After the grafts were subjected to 8 hours of cold ischemia, the release of alanine aminotransferase, aspartate aminotransferase and lactic dehydrogenase in the perfusate increased in group J (P < 0.05 vs group N); the increase was corrected in group P (P < 0.05 vs group J). When the grafts were subjected to 15 minutes warm ischemia prior to the liver harvest, the production of bile was reduced in group J (P < 0.05 vs group N); bile production was reestablished in group P (P < 0.05 vs group J). The clinical application of such a method of donor nutritional conditioning, in the hours which precede organ harvesting, may enhance the quality of the hepatic graft at the time of transplantation.

A chronic oral toxicity study of 6-amidino-2-naphthyl 4-[(4,5-dihydro-1H-imidazol-2-yl)amino] benzoate dimethanesulfonate (FUT-187), a new protease-inhibiting agent, was carried out using male and female beagle dogs. FUT-187 was orally administered to the dogs at dose levels of 7.5, 15, 30 and 60 mg/kg/day for 52 weeks, followed by 5 weeks' recovery period. Results are summarized as follows: 1. In general conditions, vomiting, salivation and the passage of mucousy stools were observed in dogs given 15 mg/kg/day or more, and diarrhea was observed at 30 mg/kg/day or more. One male given 15 mg/kg/day showed transient pallidity of the oral mucosa, and another male in the same group showed apnea and abdominal breathing. In addition, one male given 30 mg/kg/day was euthanatized due to extreme weakness, as weight loss and pallid oral mucosa, and another male in the same group died after showing acute toxic symptoms such as hyperpnea, tonic convulsion and ataxic gait. 2. Weight gain was slightly suppressed in females given 60 mg/kg/day. No significant changes in food consumption were observed. 3. Hematological examination revealed no statistically significant changes. Decreases in RBC counts, Ht values and Hb concentrations, and increased reticulocyte counts were observed in one male of 15 mg/kg/day group, which also showed pallid oral mucosa, and in one male of the 30 mg/kg/day group, which was euthanatized in a moribund state. 4. Blood biochemistry revealed increased GPT activity in males given 15 and 30 mg/kg/day and females given 60 mg/kg/day, which was accompanied by sporadic increases in GOT, A1P and/or gamma-GTP activities. Males given 30 mg/kg/day or more showed decreased total protein. 5. Hepatic function testing (ICG test) showed no statistically significant changes. One female given 60 mg/kg/day showed increased accumulating concentration of ICG. 6. There were no toxicological changes in urinalysis, fecal occult blood, renal function (PSP clearance), ophthalmological and electro-cardiographic examinations. 7. In pathological examination, inflammatory cell infiltration and microgranuloma formation in liver were noted periportally or perivenularly in both sexes given 15 mg/kg/day or more (except for 30 mg/kg/day males). In the some cases, atrophy, degeneration and necrosis of hepatocytes and/or fibrosis around inflammatory cells and microgranuloma were observed. In the spleen, one male given 15 mg/kg/day and one female given 60 mg/kg/day showed increased plasma cells in the red pulp. In the case sacrificed in a moribund condition, findings in the liver and spleen similar to those in surviving cases were detected, but were more severe, and the liver showed diffuse fibrosis.(ABSTRACT TRUNCATED AT 400 WORDS)

A subacute oral toxicity study of 6-amidino-2-naphthyl 4-[(4,5-dihydro-1H-imidazol-2-yl) amino] benzoate dimethanesulfonate (FUT-187), a new protease-inhibiting agent, was carried out in beagle dogs of both sexes. FUT-187 was administered to dogs at daily oral doses of 15, 50 and 150 mg/kg. Dogs in 150 mg/kg group were given twice a day in a.m. and p.m.. The results were as follows: 1. Changes of physical sign attributed to FUT-187, consisted of vomiting, diarrhea, salivation, decrease of locomotor activity, sedation and hyperemia of eye mucosa. These changes expect vomiting vanished within about 2 hours after treatment. One male given 150 mg/kg died on day 19 and two females given 150 mg/kg were sacrificed on day 55 and 67 due to deterioration of systemic conditions. 2. Body weight gain was suppressed in males given 150 mg/kg and females given 50 mg/kg or more. 3. In hematological examinations, some changes suggesting anemia or inflammation were observed in a few animals received 50 mg/kg or more 4. In serum biochemical examinations, dogs given 50 mg/kg or more had decrease of albumin, total protein, A/G ratio and total cholesterol, increase of GPT activity. In liver function test, decrease of function was observed in a few animals in 150 mg/kg group. These changes diminished by the end of recovery period. 5. In autopsy findings, ulcer formation and desquamation of mucosa in the digestive tract were observed in dead or sacrificed animals and survived animals given more than 50 mg/kg. In sacrificed animals, liver was yellow in color and intussusception was seen. 6. Plasma levels of intact FUT-187 and metabolites on the day 37 or 83 were higher than that on the first day of administration. 7. In histopathological examinations, ulcer formation, desquamation, degeneration and/or atrophy of mucosa in the digestive tract were observed in the animals from 50 mg/kg and 150 mg/kg groups. In addition, fatty deposition in hepatocytes was observed in one dead animal and two sacrificed animals.(ABSTRACT TRUNCATED AT 400 WORDS)

Eleven subjects performed a graded exercise test after 1 week of protein supplementation (PRO) or glucose polymer placebo (CON), randomly assigned in a double blind fashion. The exercise consisted of 3-min graded exercise bouts separated by 10 min of active recovery at zero pedal resistance. Subjects then performed a 30-sec Wingate test (WIN) to assess performance during supramaximal exercise. Blood samples were obtained in the last 15 sec of each exercise and recovery period. PRO resulted in a decrease in blood lactate following 120% VO2max and WIN, an increase in blood alanine at all time points, and lower postexercise muscle lactate and glycogen. Resting muscle GPT activity was 47% higher during the PRO trial. Mean power output during the WIN did not differ between PRO and CON. The WIN fatigue index was not significantly different between PRO and CON. The increased alanine may reflect increased transamination of pyruvate, thereby reducing the accumulation of lactate, which in turn had a marginal effect on performance during supramaximal exercise.

Over a three-year-period, 310 babies with prolonged jaundice admitted to GHKL were studied, to determine the incidence of alpha-1-antitrypsin deficiency as a cause of the problem. Ninety-two babies (29.7%) were found to be alpha-1-antitrypsin deficient. The percentage incidence was found to be highest in Indians (33.3%), followed by Malays (31.9%) and Chinese (26.7%). There was a male preponderance with a M:F ratio of 1.6:1. Most of these babies presented at the hospital at the age of more than two weeks but less than one month. Apart from the problem of prolonged jaundice and alpha-1-antitrypsin deficiency, 2 had associated bleeding problems, 11 associated infections and 3 respiratory problems. Two babies had clinical features of Down's syndrome, 2 had G6PD deficiency and 1 had congenital hypothyroidism. AST, ALT and ALPO4 were high in 20, 26 and 3 babies respectively.

The natural history of chronic hepatitis B patients who spontaneously cleared serum HBsAg was investigated. A total of 351 patients with chronic hepatitis B were observed in our hospital for at least 3 yr. Seven of these patients became HBsAg negative during the follow-up period. HBsAg disappeared within 6 mo (range = 11 to 169 days, mean = 70 days) after acute elevation of ALT. ALT levels as high as 500 IU were found in three patients, whereas such elevation was not demonstrated in the other four patients. After the disappearance of HBsAg, ALT levels returned to normal in all patients. With one exception, all patients seroconverted to antibody to HBsAg; however, hepatitis B virus DNA remained detectable in serum using the polymerase chain reaction in five patients. The titer of percent inhibition of antibody to HBcAg gradually decreased to less than 70% when a 1:200 dilution of the serum of six patients was used. Four of the patients had active liver disease develop: two had chronic active hepatitis and two had cirrhosis. Three of these four patients subsequently had hepatocellular carcinoma develop. These findings suggest that patients may suffer complications of chronic hepatitis even after normalization of transaminase activities and after the clearance of HBsAg. Thus hepatitis B virus should be considered as a possible factor associated with hepatocellular carcinoma even in the absence of HBsAg, particularly if serum hepatitis B virus DNA persists.

Five healthy male adults were deprived of food for a short period (40 hr) and biochemical studies and urinalyses were done before and after fasting to determine the effects on liver and renal functions. Acceleration in lipid metabolism was seen with an increase of about 90% in NEFA and about 20% in TG. GOT, GPT and LDH showed elevations of about 40 to 100% indicating a slight effect of 40 hr fasting on liver functions. BUN, HDL-C and ALP showed increases of about 30% while, CPK and TC showed decreases of about 20%. In the other parameters changes of about 10% were seen. After a fasting with water intake of about 1,000 ml/day, a body weight loss of 1.2 kg was observed at 40 hr. During the short-term fasting (40 hr) as done in our study, changes were seen in glucose and lipid metabolism. However, since no abnormalities were seen in general biochemical parameters, we consider that a fasting of this duration is valuable for use as one of the fastings.
