Allergization under conditions of functioning an inhibitory factor in the organism was studied by the reaction of leukocytolysis with Tsuverkalov's dysenterin and in the reproduction of hypersensitivity of the immediate type on the Schultz-Dale's model. It was shown that in functioning an inhibitory factor in the organism the degree of leukocytolysis reaction with the dysentery allergen decreased in the immunized animals in parallel with the fall in the serum antibody activity. A depression of the activity of macromolecular sensitizing antibodies was also observed.

Groups of Swiss white mice weighing 25-28 grams were infected orally with 500, 2,000, 5,000 or 20,000 oocysts of Eimeria falciformis var pragensis. Depression, anorexia, weight loss, diarrhea or dysentery, and dehydration were most pronounced at eight to ten days postinfection. The highest mortality, 31%, occurred in mice infected with 20,000 oocysts. None of the mice infected with 500 oocysts died. The pathological findings were equally severe in mice infected with 5,000 and 20,000 oocysts. The enteric lesions, most pronounced at eight to ten days postinfection, were restricted mainly to the large intestine and consisted initially of both cryptal and absorptive epithelial cell destruction and submucosal edema. These changes were followed in 12 to 24 hours by a transient influx of neutrophils into the lamina propria followed by mononuclear cell infiltration which lasted for five to ten days. As the infective dose decreased, the inflammatory response occurred later and was less extensive. When seen, hemorrhage occurred seven to 11 days postinfection. In 50% of the mice infected with 5,000 and 20,000 oocysts, varying degrees of a nonselective mucosal necrosis were seen at eight to 12 days postinfection. In mice infected with 500 oocysts, mucosal destruction was restricted to the epithelium. Neutrophils predominated when necrosis was extensive, otherwise, mononuclear cells were the main inflammatory cells. Two to three days following necrosis, crypt hyperplasia was marked and mucosal integrity was restored. Ulcers, some of which extended into the submucosa, healed by days 14 to 20. Localized granulomatous colitis, induced by trapped oocysts within the lamina propria, was seen until the experiment was terminated at 25 days postinfection. Infection was followed by lymphoid hyperplasia in the lymph nodes and the spleen.

The life cycle of a species of murine Eimeria, isolated from a commercial source of mice is described using experimental infections. A pure strain was established starting from a single oocyst administered to Eimeria-free Swiss white mice. The prepatent period was 6 1/2 to 7 days, and the patent period lasted 6 to 10 days. Oocysts were subspherical or ovoid, with a smooth double-layered colourless membrane. Micropila was absent. The sporulated oocysts measured 15.7-25.1 x 14.1-22.0 microns (X780 = 21.3 x 16.9 microns). One to 4 polar granules were present. The oocyst residuum was absent. Sporocysts were ellipsoid, measured 11.5 x 6.3 microns (n = 780), with Stieda body and a compact subspherical sporocyst residuum. The sporozoites were elongated, 17.7 x 3.2 microns (n = 100), partially curled around each other. The endogenous stages were found only in the large intestine, with at least 4 generations of schizonts. Mature 1st generation schizonts, first seen 24 hr post-infection (HPI) measured 10.3 x 10.6 microns and had 8 to 25 merozoites 5.0-10.0 x 1.0-3.0 microns. Mature 2nd generation schizonts were first seen 48 HPI, measured 14.4 x 8.1 microns and had 8 to 20 merozoites 11.0-16.0 x 2.0-3.0 microns. Two forms of presumably 3rd generation schizonts appeared between 72 and 96 HPI: one measuring 13.9 x 8.5 microns, containing large merozoites (17.0-19.0 x 2.0-4.0 microns) and the other measuring 7.3 x 10.4 microns, where 6 to 10 merozoites (8.0-13.0 x 1.0-3.0 microns) were found. Fourth generation schizonts measuring 10.4 x 11.9 microns, with 26 a 48 or more merozoites (8.0-13.0 x 2.0-3.0 microns) were first seen at 132 HPI. Mature macro and microgamonts were first observed at 144 HPI. The sporulation of 72.0% of the oocysts in 2.0% (w/v) potassium dichromate at 23-24 degrees C occurred in 9 days. Usually the infected mice showed depression, anorexia, weight loss, diarrhea or dysentery, and dehydration. The clinical picture w as more pronounced at 6 to 10 days post-infection (DPI). Mortality was highest between the 8th and 13th DPI, with a peak at 9 DPI in groups which received 1.1 x 10(4) to 4.4 x 10(4) oocysts. Groups infected with 5.5 x 10(3), 8.8 x 10(4) or 1.76 x 10(5) oocysts showed different results. Epithelial destruction, edema, inflammation, necrotizing enteritis followed by glandular regeneration and realing were observed restricted to the large intestine. The isolated Eimeria was named E. falciformis var. pragensis based on its morphobiological characteristics.

The pathogenesis of concurrent Cytoecetes phagocytophila and louping-ill virus infection was studied in two experiments. In the first experiment 18 four- to seven-year-old rams were used. Ten were infected with C phagocytophila and five days later eight of these animals and the remaining eight sheep were infected with louping-ill virus. The two rams infected with C phagocytophila alone developed no clinical signs apart from a transient pyrexia, while only three of the eight rams infected with louping-ill virus alone showed mild clinical signs. In marked contrast, all eight dually infected sheep developed severe clinical signs with pronounced depression and dysentery and three died and five were killed in extremis. They developed higher titres of viraemia and the antibody response was depressed while necrotising lesions affecting a variety of organs were detected at post mortem examination. Rhizomucor pucillus was recovered from these lesions in seven of the eight sheep. A second experiment using 10 sheep, five aged seven months and five aged two to three years, confirmed the findings of the first experiment indicating that the age of the animal had not significantly influenced the initial result. It was concluded that C phagocytophila infection could enhance the pathogenicity of louping-ill virus and that, operating together, the two pathogens facilitated fungal invasion. It is postulated that sudden deaths in sheep recently transferred to tick-infested pastures may be due to this newly described syndrome.

Results are presented of an evaluation of the contraceptive efficacy, cycle control, and tolerance of a low dose triphasic pill, Trigynon, used by 353 reproductive-aged women for a total of 1668 cycles. 20 physicians in different Belgian centers recruited and followed the women. Average weight of the patients was 56.8 kg, average age was 24.8 years, average parity was 1.07, and 1/3 smoked. None had any medical condition contraindicating the use of the preparation. 156 of the women had never used contraception, 163 had used combined pills, 4 had used injectables, 6 had used progestin-only minipills, 21 had used IUDs, and 22 had used other methods. 2.5% of the patients forgot to take at least 1 pill in a typical cycle. No pregnancies were imputed to forgetting, but 3 pregnancies occurred during the study: 1 already established but not recognized at the start of treatment, 1 in a woman taking antituberculosis drugs, and 1 in a patient suffering an attack of dysentery. Almost 90% of patients had regular cycles of 28 days with treatment, compared to only 57.5% before treatment. The duration and quantity of bleeding were significantly decreased. Compared to the last pretreatment cycle, the 3rd and 6th cycles with Trigynon showed a decrease in percentage of patients complaining of dysmenorrhea, nervousness, headaches, breast tenderness, nausea, vomiting, decreased libido, depression, thrombophlebitis, and edema. The percentage complaining of acne and vertigo increased slightly at 3 months and then declined to below pretreatment levels. Average weight was almost unchanged. It appears that Trigynon offers reliable protection, excellent cycle control and few side effects, and would be an appropriate contraceptive choice for most women except those with benign breast disease or hyperestrogenism.

An investigation was carried out on the toxicity of the leaves of Erythrophleum guineense Don. in sheep. Four groups of two animals each were fed 8, 2, 0.5 and 0.25 g/kg/day, respectively, of dried ground leaves of E guineense through a stomach tube. Two animals served as controls and received 8 g/kg/day of ground grass hay through a stomach tube. Animals which received 8 g/kg of E guineense died within 3 h; those which received 2 g/kg died within 18 h, while those which received 0.5 and 0.25 g/kg developed clinical signs after being fed for two to four days and died between two and 14 days. Clinical signs observed were coma and convulsions in animals which died within 18 h. Animals which died after several days of sickness had signs of depression, dyspnoea, groaning, trembling of hind limbs, strong heart beat and severe dysentery. Pathological changes observed post mortem were varied and occurred in a number of organs.

Symptomatic human immunodeficiency virus (HIV) infection is accompanied by depressed CD4+ T-lymphocyte counts. These cells seem to play a role in the inflammatory processes in Crohn's disease. It has even been speculated that depression of CD4+ T-lymphocytes in HIV infection may cure Crohn's disease. Here we describe a 41-year-old drug-addicted man with a 9-year history of Crohn's disease. HIV infection was diagnosed 8 years ago. At present he has stage-C3 HIV infection. He was admitted because of weight loss and chronic diarrhea with rectal blood and mucus discharge. Crohn's disease was confirmed endoscopically and histologically. Infectious diarrhea known to mimic Crohn's disease in patients with acquired immunodeficiency syndrome (AIDS) was excluded. In summary, we describe a patient with AIDS (CD4 count, 84/microliter) and active Crohn's disease, showing that both illnesses can occur simultaneously.

Most health professionals in developing and developed countries consider oral rehydration therapy (ORT) to be the most effective treatment for diarrhea. An estimated 1,500 million episodes of diarrhea occur annually and 3 million of these results in death of children 5 years old. Caretakers must give increased amounts of fluids (rice water, tea, and gruel) to children with diarrhea to prevent dehydration. If they become dehydrated, caretakers must take them to a health workers so he/she can assess and treat them with oral rehydration solution (ORS) or, in the case of severe dehydration, rehydrate them intravenously. Drugs should not be used to treat diarrhea cases. Nevertheless, surveys in 4 Asian nations indicated that drug use ranged from 22-68% of diarrhea episodes and ORS use ranged only from 9-21%. Drug use is very expensive. In fact, Peru spent US$2 million on antidiarrheals in 1988- 1989. Further, drugs often make up 40% of health care costs in developing countries, so ORS use reduces these costs. Indeed drug us deflects from correct case management of diarrhea. In addition, drugs have no proven value for acute diarrhea. They do not decrease the fluid loss responsible for death and may even have serious side effects, such as central nerve depression and gastrointestinal toxicity. If health workers suspect cholera or dysentery, however, they can administer effective and relatively inexpensive antibiotics. Since the early 1980s, almost all developing countries had a national control of diarrheal disease program. In several countries, hospital admission rates for diarrhea fell 61% and the case fatality rate fell 71% after ORT introduction. Some hospitals have even saved as much as 60% in costs due to these declines. WHO has a book available which covers rational use of drugs in managing acute diarrhea in children.

Verbena officinialis Linn. (Verbenaceae) is a perennial plant which has been used as herbal medicine or health supplement in both Western and Eastern countries for centuries. It has been used to treat acute dysentery, enteritis, amenorrhea and depression. In view of its wide array of biological effects, we hypothesized that V. officinalis can exert cytoprotective effects on cells of the central nervous system. Pre-treatment of aqueous extracts of V. officinalis significantly attenuated the toxicity of beta-amyloid (Abeta) peptide and reducing agent dithiothreitol in primary cultures of cortical neurons. As extracellular accumulation of Abeta peptide is an important cytotoxic factor involved in Alzheimer's disease (AD), we have further explored its neuroprotective effect against Abeta. Treatment of V. officinalis attenuated Abeta-triggered DEVD- and VDVAD-cleavage activities in a dose-dependent manner. Further studies elucidated that phosphorylation of both interferon-inducing protein kinase (PKR) and c-Jun N-terminal kinase (JNK) was attenuated in Abeta-treated neurons. Taken together, we have proved our hypothesis by showing the novel neuroprotective effects of V. officinalis. As V. officinalis has long been used for many years to be a folk medicine, our study may provide a lead for its potential to be a neuroprotective agent against neuronal loss in AD.

Thomas Jefferson, the third President of the USA, was often the victim of a panoply of disorders including episodic headaches, dysentery, rheumatism, multiple bone fractures, malaria, possibly tuberculosis, dental problems, diabetes and urinary tract obstruction. Intermittently he experienced anxiety, depression and insomnia; he was an anxious, striving perfectionist, a compulsively controlled man.
