Samples of faeces and blood were obtained from 66 adult horses with diarrhoea. The results of routine bacteriological, parasitological, haematological and biochemical tests were correlated with the outcome of the cases. Twenty-two (33 per cent) of the horses died or were destroyed as a consequence of the diarrhoea. A diagnosis was reached in only 23 cases (35 per cent), and in nine of them only at post mortem examination. Salmonella typhimurium was isolated from five cases. Statistical analysis revealed significant differences between the horses which survived and those which died in their packed cell volumes, white blood cell counts, neutrophil counts, serum albumin concentrations and alkaline phosphatase activities.

To study the pathophysiology of bone disorder after gastrectomy, 320 patients and 40 Wistar male rats were used. Clinically, patients who had received gastrectomy 1-15 years previously, were examined for skeletal symptoms, serum biochemistry, microdensitometry of second metacarpal bone, and 20 of them were then studied in a calcium infusion test. Using microdensitometry, abnormality of bone metabolism was observed in 38% of the patients. In severe cases, a significant decrease of serum Ca. and increase of alkaline phosphatase were observed (p less than 0.05), 65% complained of joint pain. In the calcium infusion test, severe cases showed a low urinary excretion of Ca, like osteomalacia, and unlike osteoporosis. Experimentally, body weight & amount of food intake decreased and fatty diarrhea was observed in rats after total gastrectomy. Skeletal changes including thinning of the cortex, loss of medullary trabeculation & decrease of bone ash and biochemical changes such as low serum Ca. 25(OH)D3, 24, 25(OH)2D3 and high iPTH levels were observed. Also the bone formation rate was lower than control as detected by tetracycline double labelling method. As low food intake & fatty diarrhea after gastrectomy which result in Ca. & vit. D insufficiency may be the major etiology of bone disorder.

We found 39 cases of transient hyperphosphatasemia (TH) from 8 primary medical care institutions over a 2.5 year period, beginning in 1986, and 36 cases were available for this analysis. The maximum activity of serum alkaline phosphatase (ALP) was 318 K.A unit, and 16 cases showed 100 K.A unit or more. Ages of the TH cases were ranged from 8 to 92 months and average of 25.4 months. There were no seasonal fluctuation of the incidence. Although high fever was noticed in 21 cases (58%), and diarrhea and upper respiratory infections were observed in 9 cases (25%) each, no common characteristic features in underlying diseases or laboratory abnormalities were noticed. All of those clinical signs were returned to normal within one month, except for 3 cases in which we could not make follow up study. ALP levels were re-examined within one week in 14 cases (39%) but re-examination was not requested in another 14 cases. ALP levels were returned to normal within one month but characteristic isoenzyme patterns for TH were detectable for up to 3 months from the onset. According to the investigation over 1.5 year period at Kumagaya pediatric hospital, 28 out of 7,287 samples (0.38%) were found to have TH. The mechanism to develop TH is not known, but sugar chain aberrations of ALP are more likely the cause, since viral infections were seen only a few occasions.(ABSTRACT TRUNCATED AT 250 WORDS)

Administration of pure alkaloid of T. asthamatica, suspended in peanut oil and given in single doses (12-100 mg/kg) by gavage, to male rats caused inactivity, respiratory distress, salivation, nasal discharge and diarrhoea. The oral LD50 value of the alkaloid was 35.32 mg/kg. In short term toxicity study daily doses of the alkaloid (1.25, 2.5, 5 and 10 mg/kg) were given to male rats for 15 days. Smaller doses of the alkaloid (1.25 and 2.5 mg/kg/day) produced no signs of poisoning or death in animals; while 5 mg/kg/day produced signs of poisoning and death of two animals, 10 mg/kg/day caused death of all the animals within 7 days. Activities of glutamic oxaloacetic transaminase, glutamic pyruvic transaminase and alkaline phosphatase were significant and associated with morphological changes in liver. The alkaloid also caused marked changes in the morphology of seminiferous tubules and spermatogenic activity of experimental animals. Since the alkaloid is effective in microgram quantities, the non toxic effects observed after daily doses of 1.25 mg/kg in male rats assume great therapeutic significance.

Some infants intolerant to cow's milk protein (CMP) are often also intolerant to other food proteins including soy protein (SP). The effect of CMP and SP in infants recovering from diarrhoeal disease was studied in 22 infants who were maintained on an hypo-allergenic formula for 4-6 weeks. The infants were then challenged successively, initially with SP, followed 24 h later with CMP and then rechallenged with SP 24 h after CMP provocation. Three groups were recognized on the basis of clinical symptoms and mucosal changes following SP challenge. Group 1 comprised four infants who developed clinical and histological reactions on SP challenge. The subsequent CMP challenge, 24 h after the initial SP challenge, resulted in clinical symptoms in three of the four infants, and they developed increased mucosal injury. Rechallenge with SP in the three infants caused development of severe clinical symptoms. Group 2 comprised 12 infants who developed histological reaction but had no clinical symptoms to initial SP challenge. The subsequent CMP challenge caused further progression in mucosal pathology in 11 of the 12 infants and six also had associated clinical symptoms. Rechallenge with SP in the latter six infants resulted in development of clinical symptoms in three and tolerance to SP in three infants. Group 3 comprised six infants who tolerated SP and CMP but one of these infants developed mild histological changes to CMP. The progression of mucosal injury following SP and CMP challenge was associated with a significant decrease in mucosal disaccharidases, alkaline phosphatase levels and presence of reducing sugar in the stools. The 1 h blood xylose level continued to decrease significantly following the pre-SP, post-SP, and post-CMP challenge. It appears that the small bowel mucosa of young infants recovering from diarrhoeal disease remains sensitive not only to CMP but also to SP. The feeding of these proteins in rapid successive sequence to infants with mucosal damage might result in further progression of the mucosal injury. Thus, the exclusion for a variable period of time of antigenic food proteins like CMP and SP from the diet of young infants recovering from diarrhoea might reduce the risk of inducing mucosal sensitivity to these proteins in susceptible infants.

To determine the adequacy of zinc and copper supplementation for infants receiving total parenteral nutrition (TPN), we performed 24-h balance studies in infants with diarrhea and infants who had recently undergone surgery. Measurements were made at base line, 1, and 2 wk. Mean serum Zn and Cu levels of the diarrhea group remained normal and were low in the postoperative group but normalized over the study period. Mean 24-h Zn and Cu balances were positive in infants with diarrhea and negative in postoperative infants. The high Zn and Cu content in the gastrointestinal fluid loss associated with surgery may have accounted in part for this finding. Normal serum levels of Zn and Cu did not guarantee positive balance. No significant changes were found in serum albumin, alkaline phosphatase, or ceruloplasmin. The current Zn and Cu recommendations may be appropriate only for hospitalized infants who have no excessive gastrointestinal fluid losses.

In 1983, the Northern California Oncology Group (NCOG) instituted a randomized trial of intravenous (IV) versus intraarterial (IA) floxuridine (FUDR) administered via an implantable pump for patients with colorectal cancer metastatic to the liver. The study objectives were to compare the hepatic response rate, time to hepatic progression, and toxicity for the two treatment arms. The study design, which allowed patients failing IV FUDR to crossover to the IA arm, prevents a meaningful comparative analysis of survival. Patients with liver-only metastases (N = 143) were randomized, 76 to the IV arm and 67 to the IA arm, and 115 patients (65 IV, 50 IA) were fully evaluable. Of the 65 patients in the IV arm, 28 crossed over to IA treatment after failing IV FUDR. The dose-limiting toxicity of IV FUDR was diarrhea, whereas biliary toxicity limited both the dose and duration of IA FUDR therapy. Of the first 25 patients treated with IA FUDR at a dose of .3 mg/kg/day, 10 developed radiographically evident biliary strictures, and three developed permanent jaundice. With reduction of the initial IA FUDR dose to .2 mg/kg/day, and adoption of a policy of early dosage reduction, treatment interruption, or termination of therapy for persistent elevations in alkaline phosphatase, only two further cases of serious biliary toxicity occurred. However, 26 of the 50 IA FUDR patients ultimately had therapy terminated because of drug toxicity rather than disease progression. When compared with systemic infusion, infusion into the hepatic artery greatly enhanced the antitumor activity of FUDR against colorectal liver metastases. Although biliary toxicity is the most serious limitation of this form of therapy, biliary stricture and jaundice usually can be averted through careful monitoring of liver enzymes and early dosage reduction.

Activity of alkaline phosphatase (apical membrane) and Na+, K+-ATPase (basal membrane) is determined to decrease in the membrane fractions of intestinal epithelium in the diarrheic new born cattle. It is concluded that Na+, K+-ATPase of basal membranes play a fundamental role in Na+ loss by body with diarrhea.

This investigation was initiated as a consequence of several cases of diarrhea in a nursery ward for preterm babies in Nairobi, Kenya. Ten lactose-positive colonies were isolated from the stools of each of 30 neonates, regardless of whether they had diarrhea; 229 strains were identified as Escherichia coli and 65 strains were identified as Klebsiella pneumoniae. Six strains were lost during laboratory handling. No other bacterial, viral, or parasitic enteropathogens were identified. Using synthetic alkaline phosphatase-labeled probes, the bacterial isolates were found to be negative for the presence of genes coding for heat-stable and heat-labile enterotoxins. Seventy-eight E. coli strains isolated from a total of 13 neonates possessed the E. coli enteropathogenic adhesion factor (EAF) gene, as demonstrated by the use of a cloned radiolabeled DNA fragment probe. These strains possessed similar plasmid profiles constituting a core plasmid profile, and while all adhered to HeLa cells, none produced Vero cell cytotoxins. The EAF gene was located on a 65-megadalton plasmid. Serotyping showed the strains to be of serogroup O111 and serotype H nontypable, a well known enteropathogenic type. Five neonates died during the outbreak, and the fatality rate was 30.7% (4 of 13) for neonates infected with EAF-positive E. coli strains compared with 7.7% (1 of 13) for neonates from whom only EAF-negative E. coli strains were isolated. K. pneumoniae only was isolated from five neonates.

Acute dehydration of diarrhoea of the breast-fed child is a type of hypovolemic shock which, by its severity and frequency is one of the major emergencies of pediatrics. The liver, as the site of many metabolic processes is mainly affected in the frame of the multiple-tissue involvement which is characteristic for this condition. The authors carried out a study of several enzymes (total LDH and the thermally-labile fraction, gluthamatdehydrogenase, gammaglutamyltranspeptidase, acid and alkaline phosphatase) in 27 breast-fed children. Determination of the enzymes was done on hospitalization, and 10 days later. The study showed that all the enzymes that were evaluated had moderate increases in 40.7-71% of all cases. The increases were significant (p less than 0.001). After 10 days the enzyme titers showed a tendency to become normal again, and slightly higher values were found in only 15-12% of all cases. Minimal hepatopathy can be considered, associated to the clinico-biological evolution of this severe conditions of the breast-fed child pathology.
