Several agents were employed to induce diarrhea in squirrel monkeys: (1) diarrhaogenic diets, (2) various doses of cholera toxin, (3) prostaglandin derivatives, (4) bile, (5) lactulose, (6) phenolphthalein, (7) castor oil. Kaolin, pectin, Kaopectate and placebo were used as antidiarrheal treatment. Evaluation was based on (a) frequency, (b) consistency, (c) total and dry weight of the stools, and (d) electrolyte loss. The spectrum of procedures employed appeared to be suitable for the evaluation of antidiarrheal agents of the protective and adsorbent class.

To evaluate the efficacy of antidiarrheal agents in the treatment of diarrheal illnesses, a study was conducted with children in Guatemala who had an acute diarrheal illness. Eighty patients, aged 3 to 11 years, were hospitalized and treated for two days with one of five agents: kaolin-pectin suspension concentrate (Kao-Con), kaolin suspension, pectin suspension, diphenoxylate-atropine liquid (Lomotil), or placebo. Although the patients receiving kaolin-pectin produced stools that tended to be more formed than those of the placebo-treated group patients, the study did not demonstrate any effect by any of the agents tested in influencing the frequency of bowel movement, the water content of the stools, or the weight of stools. Kaolin-pectin suspension and diphenoxylate-atropine liquid do not appear to be useful in the relief of acute nonspecific diarrhea in children.

How do you treat diarrhoea?, questionnaires were sent to 586 health workers in 81 countries and 58% replied. Treatments for acute diarrhoea were scored for popularity, including retrospective questions about therapy three years earlier. Oral rehydration was apparently widely used in 1976, and this had increased by 1979. Intravenous therapy was also important. Kaolin and sulphonamides are becoming less popular, but antibiotics are still widely prescribed. The most commonly used oral rehydration mixtures in 1979 were home made, simple salt-sugar solutions. A complete formula, as recommended by WHO, was used by a smaller number. 30% of the responders reported no difficulty with oral rehydration, but many did not favour the method. The main technical complaint in 28% of replies was that patients could not take enough fluid, and vomiting was reported in 22%. Local beliefs about the cause of diarrhoea related to some food or fluid ingested according to 45% of responders. Such diet-related beliefs may adversely affect the use of oral therapy.

Parasite levels were determined for 141 members of a naturally formed social group of rhesus macaques living under free-ranging conditions. Results indicate that group members harbor Trichuris trichiura, Balantidium coli, and large numbers of Strongyloides fuelleborni. Parasite counts decrease significantly with age in this population. Females have significantly fewer parasites than males and a significantly lower prevalence of multiple infections. There were no rank effects regarding parasitosis. While 89% of the animals examined are infected with one or more species of enteric parasite, the prevalence of diarrhea is negligible (2%). The low prevalence of diarrhea in the presence of high parasite loads may be due to the practice of geophagy, which is engaged in by 76% of group members. Soil eaten by these monkeys contains large amounts of kaolinitic clays. Kaolin-based pharmaceuticals (i.e. Kaopectate) are commonly used in human populations to treat diarrhea and intestinal upsets. The mechanical and pharmaceutical properties of the natural kaolinite-based clays may counteract the effects of parasitosis in this free-ranging population.

Despite occurring in a wide variety of taxa, deliberate soil consumption (geophagy) is a poorly understood behavior. In humans, geophagy is sometimes considered aberrant or a sign of metabolic dysfunction. However, geophagy is normally assigned an adaptive function in nonhuman primates and various other organisms. One hypothesis submits that clay-rich soil adsorbs intestinal insults, namely plant metabolites or diarrhoea-causing enterotoxins. Here we test the capacity of kaolin, a commonly ingested clay, to adsorb quinine (an alkaloid) and two types of tannin (digestion-inhibitors). Trials were conducted in vitro using the TNO Intestinal Model, a device that closely simulates digestion by the human stomach and small intestine. Kaolin reduced the bioavailability of each compound by < or =30%. However, because we could not replicate clay-epithelial adhesion and reduced motility, these results may underestimate adsorption in vivo. We also show that kaolin fails to render calcium oxalate soluble. We conclude that gastrointestinal adsorption is the most plausible function of human geophagy. Adaptive advantages include greater exploitation of marginal plant foods and reduced energetic costs of diarrhoea, factors that could account for the high frequency of geophagy in children and pregnant women across the tropics.
