A 31-year-old man presented with dull headache and memory disturbance lasting for one week. Computed tomographic scans revealed acute hydrocephalus. The cerebrospinal fluid contained 53 leukocytes/$mm^3$, with a mononuclear preponderance and no erythrocytes. Magnetic resonance imaging revealed hydrocephalus and leptomeningeal enhancement. Magnetic resonance angiography and digital subtraction angiography showed supraclinoid occlusion of the right internal carotid artery, which resembled unilateral moyamoya disease. Neuroendoscopic biopsy of a lesion in the septum pellucidum revealed noncaseating granulomas, which was consistent with sarcoidosis. The patient was successfully managed with intravenous methylprednisolone and ventriculoperitoneal shunting. To our knowledge, this is the first case of moyamoya-like vasculopathy associated with neurosarcoidosis.

This study evaluated the hazard caused by $NO_{2}$, an oxidant generated in the process of welding. We com­pared hematological and biochemical parameters in workers who chronically inhale $NO_{2}$ and office workers not exposed to $NO_{2}$. $NO_{2}$ exposure affected the hematological and biochemical parameters. Increasing $NO_{2}$ concen­trationincreased the number of leukocytes, while decreasing the number of erythrocytes. Blood urea nitrogen, cre­atinine, uric acid, and lactate dehydrogenase were increased, while total protein and triglycerides were decreased. The mean concentration of $NO_{x}(NO_{2}^{-}/NO_{3}^{-})$ in the serum of welders and the control group was $35.97{\pm}2.85\;and\;55.40{\pm}5.81\;{\mu}mol/L,$ respectively. The difference was significant (p < 0.05), although $NO_{2}^{-}$ was not detected in the serum.

This study was designed to observe the effect of tohiene pretreatment on leukocyte variation in whole blood and the oxygen free radical generating, scavenging enzyme activities in neutrophil of bacteria infected rats. Toluene was administered 7 times intraperitoneally at levels of 9.45 mM/kg body weight to the rats and then infected with S. aureus $2\times10^7$ cfu/ml. The toluene treated-rats showed the significantly decreased numbers of lymphocyte and monocytes, but the similiar numbers of neutrophils with the control. Furthermore the increased neutrophils in blood of bacteria infected rats were reduced by the toluene pretreatment. Concomitantly the increased activities of xanthine oxidase and superoxide dismutase in neutrophil of bacteria infected rats were also decreased by the toluene pretreatment. On the other hand, injection of benzaldehyde to rats also led to similiar results in the count of leukocytes, xanthine oxidase and superoxide dismutase activities of neutrophil with those of toluene treated rats. These data suggest that toluene and its intermediate metabolite, benzaldehyde influence on the phagocytosis and defence mechanism of neutrophil.

Chromosome complements of Japanese quail (Coturnix coturnix japonica) were studied using several tissues which involving testis, leukocytes and embryos. The diploid count was estimated to be 2n＝78. Analyzing the metaphase of secondary meiosis in spermatocytes, the haploid count estimated to be n＝39. Morphometric analysis were studied by the centromeric index and relative length of 8 macro-chromosomes and Z, W chromosomes The differences of morphological feature were not significant among tissues. Exceptionally the chromosome 4 shelved a considerable variety in the presence of it's short arm.

To study the immunomodulatory effect of aquapuncture with canine parvovirus killed vaccine, the vaccine was inoculated into the dogs twice with on 2-week interval. The 6 dogs in the experimental group were inoculated through the Jiao-Chao acupoint, and 5 dogs in the control group were done subcutaneously. The antibody titer was determined by the hemagglutination inhibition test. The HI titers of the experimental group showed significantly higher on days 21 and 28 than those of the control group. The biochemical test on serum total protein, protein fractions and the A/G ration showed a slightly increased in $\gamma$-globulin on days 21 and 28. The hematological findings on total leukocytes and differential counts showed no significance. It was thought that the aquapuncture of the canine parvovirus killed vaccine through the Jiao-Cho acupoint may stimulate the antibody production.

This paper reviews the mechanisms effecting host defense in the mammary gland and assesses their possible in preventing of bovine mastitis. The streak canal is the first line of defense against invading mastitis pathogens, providing a physical barrier and antibacterial substances. The milk leukocytes are a second defense line by ingesting pathogens breached the streak canal by multiplication, physical passage, and propulsion during milking. Leukocytosis in milk and enhancement of the phagocytic defense machanisms of the udder were accomplished by inserting intramammary devices. Milk antibodies serum derived and synthesized in mamma tissue aggregate and opsonise bacteria, agglutinate and neutralise toxins, and inhibit. binding of bacteria to epitherial surfaces. Vaccination generally has been unsuccessful because protection is not absolute, but immunization is useful in controlling specific pathogens. Immunostimulant to enhance locally the protective nature of antibody-producing plasma cells concentrated in internal teat end tissue may be effective in reducing the occurrence of infection, but ineffective in preventing intramammary infections.

This is the first recorded case of Sarcoptes scabiei in a Korean female raccoon confirmed by light and scanning electron microscopies. Grossly the skin on the abdomen head and legs was markedly thickened with alopecia and encrustation. histopathologically skin showed epidermal hyperplasia with spongiotic degeneration and parakeratosis. Ectoparasites were present in superficial and deep epidermal layers. Small numbers of leukocytes predominantly neutrophils were associated with the parasitic infestation. Scanning electron microscopy examination of affected skin scraping demonstrated round to oval parasitic mites measuring approximately 180 -250 x 220 - 350 um in size. The mites possessed four pairs of legs of which the two anterior pairs appeared relatively long with unjointed stalks while the two posterior leg pairs were rudimentary. these morphological features were consistent with Sarcoptes scabiei.

A 16-year-old female Bengal tiger (Panthera tigris tigris) infected with Paragonimus kellicotti was described. Noticeable clinical symptom was not observed before death. At autopsy, numerous cysts were found on the pleural surface of the lung. The cysts were spherical, approximately 1.0 cm in diameter, bulge the pleura, and dark red-brown in color. Such cysts were also found in the deeper lung parenchyma, and usually contained adult flukes in pairs. Histopathologically, the cyst was lined with stratified squamous epithelium which arose from metaplasia of bronchial epithelium. Partial hyperplasia and necrotic foci accompanied with inflammatory cells were often observed in the squamous epithelium. The outer part of the cyst was consisted of fibrous connective tissue in which leukocytes were infiltrated. Catarrhal pneumonia was manifested in the adjacent lung tissues.

Effects of zinc chloride (Zn) on the immune responses of lipopolysaccharide (LPS) were studied by using ICR mice. Mice were divided into 4 groups (10 mice/group), and Zn was given to the mice with i.p. injection at 0.3 mg/kg 5 times a week for 14 days, and 1 hr after Zn administration, LPS was given with i.p. injection at 5 mg/kg twice a week. Mice were immunized and challenged with sheep red blood cells (SRBC). Immunobiological responses were evaluated by humoral, cellular and nonspecific immunity. LPS treatment significantly increased the relative weights of spleen and thymus, hemagglutination titer (HA) and proliferation of splenocytes compared with those in controls, but significantly decreased the body weight gain. Zn treatment significantly increased proliferation of splenocytes and circulating leukocytes compared with those in controls. Combination of Zn and LPS significantly decreased the body weight gain and proliferation of splenocytes compared with those in controls. Combination of Zn and LPS significantly decreased HA and proliferation of splenocytes than in LPS alone. These findings indicate that zinc lowered the humoral immune responses of LPS.
