The chronic toxicity of potassium clavulanate (CVA-K) and BRL28500 were evaluated using dogs in 26-week intravenous administration studies followed by a 5-week off-dose period. The doses for CVA-K and BRL28500 were 10, 20, 50 and 100 mg/kg (p.f.a.), and 80, 160, 320 and 800 mg/kg (p.f.a.) respectively. There were no deaths in either of the groups. For general condition, dogs dosed with CVA-K at 100 mg/kg showed reddening of the skin and mucous membranes, shaking of the head, facial oedema, a decrease in food intake and a reduction in body weight. Also some dogs of the same group showed decreased spontaneous activity, emaciation and signs of dehydration. In the BRL28500 treatment groups, there was reddening of the skin and mucous membranes, vomiting and salivation at 800 mg/kg. Urinalysis of dogs dosed with CVA-K showed occasional dark yellow coloration of the urine. There was also a very weak and equivocal response or positive reaction for protein, occult blood, and urine sugar in some animals at 100 mg/kg. Some dogs dosed with BRL28500 also showed either a very weak and equivocal response or slight positive reaction for occult blood at 320 mg/kg and above, and dark yellow coloration of the urine at 800 mg/kg. Haematological examination of the CVA-K groups showed increases in leukocyte count and platelet count at the highest dose of 100 mg/kg. No haematological abnormalities were noted in any of the BRL28500 groups. Serum biochemical studies of dogs dosed with CVA-K revealed a decrease in total protein at 50 mg/kg and above, and increases in Al-P, total bilirubin, GPT, BUN and creatinine at 100 mg/kg. In the BRL28500 treatment groups, there were increases in total cholesterol and triglyceride at 160 mg/kg and above. In dogs dosed with CVA-K there was an increase in liver weight at 100 mg/kg. Histopathological examination showed a ground glass-like appearance of the hepatocyte cytoplasm and also altered distribution of PAS positive material at 50 mg/kg and above. In the BRL28500 groups, there was an increase in liver weight at 320 mg/kg and above. There were the same ground glass-like appearance in hepatocytes and altered distribution of PAS positive material at 800 mg/kg. In view of the above results, the maximum non-effect dose levels in the present studies were considered to be 20 mg/kg for CVA-K and 80 mg/kg for BRL28500.(ABSTRACT TRUNCATED AT 400 WORDS)

A 1-day-old male infant with congenital short small bowel was transferred to our hospital because of bilious vomiting and abdominal distension. An exploratory laparotomy performed at the age of 8 days revealed malrotation without any volvulus or stenosis of the small intestine, which was 45 cm long. There were no other anomalies except absence of the appendix. Postoperative nutritional support was by intravenous hyperalimentation and administration of elemental diet. However, parenteral nutrition was discontinued because of hyperbilirubinaemia. The patient died from marked emaciation at 2 months of age despite the administration of elemental diet. Therefore, careful total parenteral nutrition is the only management for successful therapy until the child's intestinal absorptive function develops.

Three cases of diencephalic syndrome, associated with brain tumors, are reported in this paper. Case 1. A 2-2/12-year old boy was initially admitted to our hospital because of failure to thrive which began at the age of three months. Physical examination revealed emaciation (weight, 7.8 kg), irritability and pallor without anemia. Horizontal nystagmus was seen. Laboratory studies were normal except for abnormally high plasma growth hormone (p-GH) which was incompletely suppressed by hyperglycemia (induced by glucose) and was not elevated by hypoglycemia (induced by insulin). A low grade astrocytoma of the optic nerve compression the hypothalamus was partially removed. After the operation followed by irradiation, p-GH returned to normal both in its basal level and in its reaction to insulin loading, then his gain of weight was accelerated. He was readmitted, however, at the age of 6 8/12 years with headache and vomiting. Since subtotal removal of the recurrent tumor and irradiation, preoperative symptoms have disappeared up to the present (7 9/12 years old). Case 2. A 3-9/12-year old girl was initially admitted because of failure to thrive since the age of 2 years. Examination on admission revealed emaciation (10.5 kg), irritability and right hemiparesis. Laboratory studies were normal except for high serum cholesterol (290 mg/dl). (p-HG was not measured) The patient had been well after the subtotal removal of the hypothalamic astrocytoma except occasional headache until the age of 6 years. She was readmitted at the age of 9 years with progressive emaciation.(ABSTRACT TRUNCATED AT 250 WORDS)

A toxico-allergo-asthenic syndrome, primarily detected as a group disease (16 cases) affecting the workers of a cattle-ranch with the record of halproviosis (chlamydiosis) of agricultural animals, is described. A rise in temperature, sickness, vomiting, headache, loss of appetite, pain in the jaws and the joints, conjunctivitis and episcleritis, frequent urination, weakness, irritability, emaciation appeared to be its most characteristic symptoms. The halprovial nature of this syndrome was revealed on the basis of differential clinico-laboratory studies, serological, epizootic and epidemiological data.

Of 109 dogs submitted with complications following ovariohysterectomy, twenty were found to show enterological problems. Presenting symptoms in these animals consisted in vomiting, diarrhoea and emaciation. A large number of animals also showed body temperatures above 39 degrees C. An irregular, often painful mass was palpable on examination of the mesogastrium in seventeen cases. Plain radiography revealed the features of ileus in ten dogs, a mass of soft tissues in the abdominal cavity in six and the pattern of peritonitis in five cases (two animals were classifiable with two groups). One dog did not show any changes. Laparotomy was performed in all twenty dogs. In view of the extent of the lesions, euthanasia was performed in ten animals. Partial enterectomy was performed in the other ten; some of these dogs are still alive at the time of writing. The findings at laparotomy and subsequent post-mortem examination, if any, may be summarized as follows: - there were adhesions between the ovarian-stump granulomas and an intestinal loop in five animals; - twelve animals showed adhesions between the ovarian-stump granuloma and the intestines which also adhered to each other; in five of these bitches, the intestinal loops were also attached to the wall of the abdomen, and also to the cervix stump in two cases; - three dogs only showed adhesions between intestinal loops; the cervix stump was involved in the adhesions in one dog.

Phentyrin toxicity depends to a large measure on the route of its administration. Adequately toxic doses of phentyrin intravenously are approximately ten times as less compared to peroral administration. High doses of the drug produce appetite loss, occasional vomiting, salivation, diarrhea, flabbiness and weight loss. ECG shows slow pulse, reduced voltage and changes in T wave. At early periods the animals' death ensues with phenomena of emaciation, a delayed death can be recorded only in some cases. Morbid anatomy shows atrophic changes in the lymphatic nodes, in the spleen, thyroid, in the gastrointestinal mucosa, and changes in the liver and kidneys. Phentyrin in tolerated doses exerts no adverse action on stem cells of bone marrow, but affects spleen cells. The drug alters the weight of some endocrine organs -- the thyroid, uterus and adrenals.

Five Karan Swiss crossbred (Sahiwal x Brown Swiss) calves were abruptly switched over from a diet of concentrate and maize fodder to ad libitum air dried Leucaena leucocephala leaves plus twigs. After 17 days on the L. leucocephala diet, 3 of the calves were supplemented with copper sulphate (10 mg/kg DM L. leucocephala) for 12 days. Thereafter all the calves were taken off the L. leucocephala diet and returned to the pre-experimental concentrate and maize fodder diet. While on the L. leucocephala diet, the average DM intake/d of L. leucocephala declined to 497 g within 3 weeks and all calves lost weight. This weight loss was reversed in the 3 calves that received copper sulphate, and all calves gained weight when they resumed the concentrate and maize fodder diet. The toxic effects of L. leucocephala feeding for 24 days were characterised by poor growth, emaciation, alopecia, loss of hair from the tail switch, ear and eye lesions, ulceration of the mouth region, drooling viscid saliva and vomiting of thick green saliva in one of the calves. Mean levels of 3,4 dihydroxypyridone (DHP) (mg/100 ml) were 30.35 +/- 13.52 and 55.57 +/- 13.77 on days 2 and 4 respectively in rumen liquor and up to 136.01 +/- 80.18 in urine. The mean ratios of mimosine: DHP of 3.14, 0.12 and 0.04 in feed, faeces and urine respectively revealed extensive degradation of mimosine to DHP in the calves fed the L. leucocephala diet and it was concluded the calves were unable to tolerate a diet consisting solely of L. leucocephala.

Anorexia and emaciation are symptoms which can be found in many diseases either singly or in combination with other unspecific clinical signs such as diarrhea and vomiting. Therefore accurately assessing the medical history, performing a thorough clinical examination and carrying out laboratory tests are all necessary steps in establishing a diagnosis. Further specific examinations such as radiography, ultrasonography or endoscopy may also have to be performed. Since anorexia and emaciation can result in severe consequences for the organism, establishing a definitive diagnosis is important to enable the appropriate therapy to be applied without delay.

A single dose toxicity of calcipotriol (MC903), an anti-psoriasic agent, administered subcutaneously (s.c.) and percutaneously (p.c.) was studied in Slc:SD rats (s.c. and p.c.) and beagle dogs (s.c.). The LD50 values of MC903 were as follows: rats, 2.19 mg/kg in males and 2.51 mg/kg in females by s.c., and more than 15 mg/kg in both sexes by p.c.; dogs, more than 1.5 mg/kg in males by p.c. No sexual difference was noted in LD50 values of rats. Death of rats was observed from 1 to 3 days after administration by both routes. Dead animals showed decreases in body weight and locomotor activity, reddish tear, abnormal gait and dirty hair by both routes. Furthermore, dead animals administered by s.c. showed salivation, nasal discharge, piloerection, ptosis, diarrhea, urorrhea, nasal and vaginal bleeding, subnormal temperature, loose stool, cyanosis, irregular and deep respirations, clonic and tonic convulsions. Survival of rats showed similar signs to those of dead animals except for nasal discharge, nasal and vaginal bleeding, cyanosis, agonal respiration and convulsion. Discoloration of the kidney, white patch of the heart and a dilatation of the stomach wall were observed on macroscopic examinations. No mortalities were observed in dogs which showed vomiting, conjunctival congestion, circumoral and auricular reddenings, periblepharal purplish reddening, decreases in locomotor activity and defecation, emaciation, eye discharge, skin desquamation of treated area and an increase in respiration. On macroscopic examination, desquamation of the skin, reddening of the circumoral mucosa, pale gray yellow striations in renal tubules of the cortex and discoloration of the thyroid were observed. Histopathological findings revealed epidermal thickening with parakeratosis, fibrocytes, hypertrophy and hypersecretion of the sebaceous and sweat glands, formation of epitheloid glanulomas and infiltration of neutrophils in the subcutaneous tissues. Furthermore, moderate calcium deposits in the renal tubules, fatty cells and slight calcium deposits in interstitial tissues of the thyroid, and a cystic nest of an ectopic intestinal epithelium between muscle layers of the duodenum were observed at the highest dose. On the basis of results obtained in the present study, rats administered MC903 by s.c. or p.c. died probably due to the circulatory and renal disturbance resulted from effects of this drug on the heart and kidney.

S-1, an antineoplastic formulation of a fluorinated pyrimidine derivative containing tegafur (FT), CDHP, and potassium oxonate (Oxo) in a molar ratio of 1:0.4:1, was recently developed by Taiho Pharmaceutical Co., Ltd., with the aim of prolonging the effective plasma concentration of 5-fluorouracil (5-FU) over that produced by FT alone and reducing its dose-limiting gastrointestinal toxicity. As a part of the S-1 toxicity study, the single-dose toxicity of S-1 as well as that of its components, CDHP and Oxo, was investigated in mice, rats, and dogs. The following results were obtained. 1. In mice and rats, excretion of diarrheal stools, salivation, and alopecia were observed after S-1 administration. In severe cases, the animals subsequently showed emaciation due to weight loss or suppressed weight gain, decreased spontaneous motor activity, an anemic appearance, bradypnea, prone position, and death. In the CDHP and Oxo treatment groups of rats, the only toxic signs were soft or diarrheal stools on the dosing day. 2. In dogs, vomiting and excretion of diarrheal, mucous, or soft stools was observed after S-1 administration. In the CDHP and Oxo treatment groups, excretion of soft and diarrheal stools and vomiting were observed relatively frequently from the dosing day until day 1. 3. In the pathological examination of the animals given S-1, mice and rats showed pulmonary congestion/edema, dark red discoloration of the mesenteric lymph nodes, atrophy of lymphatic tissues such as the thymus and lymph nodes, decreases of lymphocytes in the splenic white pulp and mesenteric lymph nodes, a decrease in bone marrow cells, congestion of the glandular stomach, and aggregates of bacteria in the lung, liver, or spleen. In dogs, abnormal changes were observed mainly in the lymphatic organs such as the thymus and lymph nodes. 4. The LD50 values of S-1 in terms of the amount FT they contained were estimated to be 549 mg/kg for mice(male), 441-551 mg/kg for rats (both sexes) and about 53 mg/kg for dogs (male). The LD50 values of CDHP and Oxo were 2000 mg/kg or higher for both rats (both sexes) and dogs (male). 5. Hematopoietic and lymphatic impairments, immunosuppression associated with respiratory were considered to be the cause of death from S-1. The toxicity of S-1 reflects the toxicity of 5-FU and was not found the different toxicity by the addition of CDHP and Oxo.
