The nomenclature, life cycles, and pathogenicity of Sarcocystis of domestic animals are reviewed. Sarcocystis had a 2-host life cycle, with carnivores as definitive hosts and herbivores as intermediate hosts. The following species are found in domestic animals (with the definitive hosts given in parentheses): 3 species in the ox: S cruzi (dog, wolf, coyote, raccoon, fox), S hirsuta (cat), S hominis (man, monkey); 2 species in the sheep: S ovicanis (dog), S tenella (cat); 3 species in the pig: S miescheriana (dog), S porcifelis n sp (cat), S porcihominis n sp (man); and 1 species in the horse: S bertrami (dog). Sarcocystis cruzi, S ovicanis, and S porcifelis are highly pathogenic to the ox, the sheep, and the pig, respectively. Clinical signs of acute bovine sarcocystosis are: anorexia, pyrexia (42 C, or more), anemia, cachexia, enlarged palpable lymph nodes, excessive salivation, and loss of hair at the tip of the tail. Anemia, anorexia, ataxia, and abortions are the chief clinical signs of acute ovine sarcocystosis. These signs are evident at the time of vascular endothelium is parasitized by schizonts. The schizonts disappear in about 1 month, and cysts are formed in the muscles. The cystic phase of sarcocystosis is virtually nonpathogenic. Carnivores shed sporocysts in their feces after ingesting the intramuscular cysts from the herbivores. Sarcocystis is nonpathogenic to the definitive host. Feline and canine coccidia are also reviewed. The following 11 species are found in cats: Toxoplasma gondii, Hammondia hammondi, Isospora felis, Isosporarivolta, Besnoitia besnoiti, Besnoitia sp, and 5 types of Sarcocystis (S hirsuta from the ox, S tenella from the sheep, S muris from the mouse, S porcifelis from the pig, and Sarcocystis sp from Grant's gazelle). The following 10 species are found in canine feces (Isospora canis, Isospora ohioensis, Isospora wallacei n sp; and 7 types of Sarcocystis (S cruzi from the ox, S ovicanis from the sheep, S bertrami and Sarcocystis sp from the horse, S miescheriana from the pig, S hemionilatrantis from mule deer, and Sarcocystis sp from Grant's gazelle). The history of Isospora begemina in dogs is reviewed; life cycles of feline and canine coccidia are given; oocysts of common feline and canine coccidia are compared and illustrated; and public health significance of Toxoplasma gondii oocysts is discussed, especially in relation to cats in the household of pregnant women.

Temporal arteritis (granulomatous inflammation) usually involves the temporal and ophthalmic arteries, but may be part of a more widespread inflammation of the medium and large vessels. The patient usually presents with an associated group of constitutional symptoms (fever, malaise, anorexia, weight loss, anemia) and rheumatic complaints (polymyalgia rheumatic complaints (polymyalgia rheumatica). The diagnosis should be considered in any patient over 55 years old in whom these symptoms develop or in whom there is evidence of recent onset of headache, visual loss of localized arterial involvement. The diagnosis is also to be considered when the erythrocyte sedimentation rate is over 50 mm/hr, and the presence of arteritis is confirmed by temporalartery biopsy findings. Visual loss may occur in 50 percent of affected patients; other serious complications are less common. A strong clinical suspicion of temporal arteritis will permit diagnosis of the more uncommon and atypical presentations of the syndrome. Although cases of temporal arteritis may be self-limited, treatment is imperative because of the threat of blindness. Patients respond well to steroid (prednisone) therapy, which should be maintained for a prolonged period.

Preliminary results of this retrospective-prospective analysis of renal hypertension in 110 children indicate that hypertension may be secondary to a wide variety of acute progresive, and chronic renal diseases which may be either congenital or acquired. Affected children may be detected at any time from infancy through adolescence. Symptoms usually associated with acute glomerulonephritis (i.e., headache, swelling, nausea, vomiting, anorexia, fatigue, dizziness, and fever) occur in both acute and chronic renal diseases associated with hypertension. Headache and swelling are the most common symptoms in this series. Peripheral edema, rales, and increased heart size were found in between 10 and 25% of these children. Differential diagnosis may be approached by a consideration of causes of acute and chronic hypertension. The child with chronic renal disease usually presents with a long history of fatigability, poor growth, and pallor, and laboratory tests reveal elevation of the creatinine and BUN along with anemia, hypocalcemia, and hyperphosphatemia. In contrast, the child with acute renal disease and hypertension presents with a history of prior good health followed by the abrupt onset of signs and symptoms of renal disease; laboratory tests usually reveal modest elevations of creatinine and BUN, anemia is unusual, an abnormal urinalysis is common, and serum calcium and phosphorous levels are usually normal. Renovascular and asymmetric renal parenchymal disease represent uncommon but important conditions because surgery may be curative. Treatment may be surgical, medical, or combined. Surgical conditions include renal trauma, hydronephrosis, asymmetric renal disease, and renal arterial disease. Adequate blood pressure control without medication can be expected following surgery in instances of unilateral involvement with a normal contralateral kidney. Meticulous assessment of the contralateral kidney is needed to determine that it is normal. If surgery is unsuccessful or is not indicated, pharmacologic therapy is initiated with a stepwise regimen starting with the mildest agent (e.g., thiazides) and then adding additional antihypertensive drugs when adequate blood pressure control has not yet been achieved. The goal of therapy is the lowest, safest, tolerated blood pressure levels. Long-term, carefully designed studies of antihypertensive agents for children with renal hypertension are not available. The need for collection and critical analysis of data concerning the clinical course of children with renal hypertension is evident from a review of the literature and from the preliminary data presented in this series. The presentation of such information and a critique of outcome variables will provide a basis for program planning for affected children and improvement in patient care where indicated.

Molybdenum toxicity and the interactions between copper, molybdenum and sulphate are reviewed. The main signs of molybdenum poisoning are poor growth and anaemia (rat, chick, rabbit, cattle and sheep), anorexia (rat), diarrhoea and achromotrichia (cattle and sheep), joint and bone deformities (rat, rabbit, cattle), central nervous system degeneration and loss of crimp in wool (sheep). The following topics are discussed: (1) The effect of sulphate and sulphur compounds on molybdenum toxicity. (2) The effect of molybdenum on tissue copper levels. (3) The effect of molybdenum on the distribution of copper in plasma. (4) The effect of molybdenum on uptake and excretion of copper. (5) The possible existence of copper(II) molybdate in vivo. (6) The influence of molybdenum on sulphide production by ruminal micro-organisms. (7) Competition between molybdenum and sulphate in intestinal transport. (8) Interaction of sulphur with copper in vivo. (9) The possible involvement of molybdenum in gout and multiple sclerosis in humans.

The acute intoxication in 4 sheep, due to an extract from a Byssochlamys nivea culture containing patulin is attained by administering per os with a syringe or with an esophagal tube doses of patulin varying from 15 to 50 mg per kg of bodyweight. A dose of 20 mg/kg, given with a syringe, brought on the death of a sheep within 5 hours following the administration, while a dose of 50 mg/kg given by an esophagal tube, only led to some temporary and slight problems. Intoxication brings on such symptoms such as nasal discharge, the stoppage of ruminating, a painful sensitivity in the retro-sternal area, weight loss, and prolonged loss of appetite. With an autopsy, a sero-fibrinous peritoneal exsudate and considerable hemorrhaging in the abomasum can be found. Anatomo-pathological examinations pinpoint lesions in the liver and kidneys. Biochemical examinations revealed hemoconcentration followed by anemia, and a considerable drop in serum proteins. The urea level increases 24 hours after and attains a notable maximum at the 30th hour (50 to 200 per cent). During these acute intoxications, no disorder whatsoever in the nervous system was observed.

Three groups of rabbits (A, B, and C; 6 rabbits/group) were fed a lead supplement of 25, 50, and 100 mg of Pb/kg of live weight/day for 87 days to compare the efficacies of 3 diagnostic tests--whole blood lead concentration, urinary delta-aminolevulinic acid (UALA), and fluorescent erythrocyte test (FET)--and to determine the clinicopathologic changes of experimentally induced lead poisoning in rabbits. All rabbits given lead had whole-blood lead concentrations greater then the maximum value (0.030 mg/dl) for control rabbits (group D), indicating that this measurement is a reliable indicator of lead ingestion. All group A rabbits (fed 25 mg of Pb/kg) and 66% negative UALA test results, with values less than the maximum value (0.12 mg/dl) for group D (control) rabbits. Only group C rabbits (fed 100 mg of Pb/kg) had consistently positive UALA FINDINGS. The test was therefore considered unreliable for detecting daily lead intakes less than 100 mg/kg of live weight of rabbits. All rabbits given lead had erythrocytes which fluoresced red when exposed to light rays with wavelenghts from 320 to 400 nm; fluorescence was not observed in erythrocytes of control rabbits. The FET appears to be a convenient and reliable diagnostic test for lead ingestion. In groups B and C, clinical signs of lead poisoning were mild, nonpersistent anemia characterized by the presence of poikilocytes, hupochromic erythrocytes, target cells, erythroblasts, erythrocytes with punctate basophilic stippling, reduced mean corpuscular hemoglobin concentrations, and relative lymphocytosis, neutropenia, and eosinopenia. One rabbit from the group fed the largest dose displayed partial anorexia.

Shi-Quan-Da-Bu-Tang (Ten Significant Tonic Decoction), or SQT (Juzentaihoto, TJ-48) was formulated by Taiping Hui-Min Ju (Public Welfare Pharmacy Bureau) in Chinese Song Dynasty in AD 1200. It is prepared by extracting a mixture of ten medical herbs (Rehmannia glutinosa, Paeonia lactiflora, Liqusticum wallichii, Angelica sinesis, Glycyrrhiza uralensis, Poria cocos, Atractylodes macrocephala, Panax ginseng. Astragalus membranaceus and Cinnamomum cassia) that tone the blood and vital energy, and strengthen health and immunity. This potent and popular prescription has traditionally been used against anemia, anorexia, extreme exhaustion, fatigue, kidney and spleen insufficiency and general weakness, particularly after illness. In order to restore immunity in cancer patients, potentiate the therapeutic effect and ameliorate adverse toxicity of anticancer agents, 116 Chinese herbal formularies (Kampo) have been screened and evaluated. Fifteen compounds were found to have such actions. Among these, SQT was selected as the most effective as a potent biological response modifier. During the last eight years, animal models and clinical studies have revealed that SQT demonstrates extremely low toxicity (LD50 > 15 g/kg op murine), self-regulatory and synergistic actions of its components in immunomodulatory and immunopotentiating effects (by stimulating hemopoietic factors and interleukins production in association with NK cells, etc.), potentiates therapeutic activity in chemotherapy (mitomycin, cisplatin, cyclophosphamide and fluorouracil) and radiotherapy, inhibits the recurrence of malignancies, prolongs survival, as well as ameliorate and/or prevents adverse toxicities (GI disturbances such as anorexia, nausea, vomiting, hematotoxicity, immunosuppression, leukopenia, thrombocytopenia, anemia and nephropathy, etc.) of many anticancer drugs. The application and mechanistic studies of SQT in future development have potential importance in basic and clinical research of the traditional Chinese therapeutic approach of "toning the blood and strengthening Qi (vital energy)" in cancer immunotherapy.

A 9-month-old sexually intact male longhair cat was examined because of lethargy, anorexia, cold intolerance, and failure to thrive since acquisition at an early age. Clinical signs of disease were less pronounced when the cat was fed a low-protein diet. Anemia, hypoglycemia, low total CO2 content, and hyperammonemia were detected. The cat was euthanatized. Urine obtained immediately before euthanasia contained a large amount of methylmalonic acid. Total serum cobalamin concentration was low. Hepatic methylmalonic-CoA mutase activity, with and without the addition of coenzyme adenosylcobalamin, was consistent with a cobalamin deficiency. Methylmalonic acidemia secondary to a putative defect in cobalamin absorption was diagnosed.

A systemic necrotizing vasculitis of unknown etiopathogenesis may be termed juvenile polyarteritis syndrome (JPS). The syndrome has been recognized primarily in young Beagles used for toxicologic studies. We studied 9 young Beagles with JPS. Affected dogs had fever (40 to 41.5 C), anorexia, and signs of pain in the cervical area. They had a characteristic hunched stance, and were unwilling to move. Laboratory abnormalities in all dogs included nonregenerative anemia, hypoalbuminemia, and leukocytosis characterized by a mature neutrophilia. Analysis of CSF revealed a moderate to severe neutrophilic pleocytosis and a mildly high protein concentration in most dogs. Signs of disease resolved rapidly with high doses (2.2 mg/kg of body weight, PO) of prednisone. If untreated, clinical signs and laboratory abnormalities had a remitting and relapsing course in most dogs. Findings at necropsy included necrotizing arteritis with fibrinoid necrosis, periarteritis, thrombosis, and intimal proliferation that most frequently affected small- to medium-sized vessels in the cervical spinal cord, mediastinum, and heart. An immune-mediated pathogenesis for this disease is suspected.

A novel canine retrovirus was isolated from mononuclear cells of the peripheral blood of a leukaemic dog. The main clinical and pathological findings in this dog were lethargy, anorexia, weakness, dyspnoea, severe anaemia, thrombocytopenia and a high white blood cell count, practically all of which were lymphoblasts. The virus was isolated from mononuclear cells obtained from the blood, cocultivated with indicator cells. The virus particles encode a reverse transcriptase with Mg++ preference, have a density in sucrose gradients of 1.16 g ml-1, and induce syncytia in permissive cell cultures such as Himalayan tahr ovary and canine fetal thymus lines. This agent replicates to high titres. The virus exhibits a morphogenesis and morphology typical of lentiviruses. Immunoblotting and competitive radioimmunoassays failed to detect immunological crossreactivity with other representative lentiviruses and oncoviruses of the retrovirus family.
