Inflammatory skin diseases such as atopic dermatitis (AD) and rosacea were complicated by barrier abrogation and deficiency in innate immunity. The first defender of epidermal innate immune response is the antimicrobial peptides (AMPs) that exhibit a broad-spectrum antimicrobial activity against multiple pathogens, including Gram-positive and Gram-negative bacteria, viruses, and fungi. The deficiency of these AMPs in the skin of AD fails to protect our body against virulent pathogen infections. In contrast to AD where there is a suppression of AMPs, rosacea is characterized by overexpression of cathelicidin antimicrobial peptide (CAMP), the products of which result in chronic epidermal inflammation. In this regard, AMP generation that is controlled by a key ceramide metabolite S1P-dependent mechanism could be considered as alternate therapeutic approaches to treat these skin disorders, i.e., Increased S1P levels strongly stimulated the CAMP expression which elevated the antimicrobial activity against multiple pathogens resulting the improved AD patient skin.

We report nutritional physiology and non-specific immune responses of vitamin E in parrot fish for the first time. This study aimed to investigate the essentiality and requirements in diets based on growth performances, non-specific immune responses and a challenge test against Vibrio angullarum. Six casein-gelatin based semi-purified diets were formulated to contain six graded levels of DL-${\alpha}$-tocopheryl acetate (${\alpha}$-TA) at 0, 25, 50, 75, 100 and 500 mg/kg diet (designated as E0, E25, E50, E75, E100 and E500, respectively) and fed to triplicate groups of juvenile parrot fish for 12 weeks. The analyzed dietary concentrations of vitamin E were 0, 38, 53, 87, 119 and 538 mg/kg diet for E0, E25, E50, E75, E100 and E500, respectively. At the end of the feeding trial, growth performance and feed utilization of fish fed the E25 were significantly higher compared to that of fish fed the other diets. Liver ${\alpha}$-tocopherol concentration was significantly increased with an increase in dietary ${\alpha}$-TA in a dose dependent manner. No apparent clinical signs of vitamin E deficiency and mortality were observed in fish fed the basal diet for 12 weeks. Among the immune responses assayed, phagocytic (NBT assay) and myeloperoxidase activities were significantly increased with increment of dietary ${\alpha}$-TA levels. During the challenge test with V. anguillarum, E75, E100, and E500 diets resulted in higher survivals than E0, E25 and E50 diets. The findings of this study suggest that parrot fish require exogenous vitamin E and the optimum dietary level could be approximately 38 mg ${\alpha}$-TA/kg diet for normal growth and physiology. Dietary ${\alpha}$-TA concentration over 500 mg/kg could be required to enhance the nonspecific immune responses and improve the resistance of juvenile parrot fish against V. anguillarum.

Herpes zoster is an infection by the varicella zoster virus in a partly immune compromised person such as old age, cancer, immune deficiency disease. When either the upper lumbar or sacral segments are involved, serious urinary retention caused by central spread of herpes zoster from dorsal root ganglion can occur. The urinary disturbance appears to have been due to motor dysfunction of detrusor muscle, trigone muscle, and internal sphincter. We experienced two cases of zoster affecting different segments of the spinal cord and resulting in urinary retention.

Infection by aspergillus, which is a kind of mold, or a filamentous fungus, occurs rarely in larynx. Furthermore, primary laryngeal aspergillosis without any other airway tract extension and without any generalized immune deficit is extremely rare. We present a case of primary aspergillosis on vocal cord in a 72-year-old male who had no history of immune deficiency, voice abuse or steroid use.

Activated T cells express inhibitory receptors such as CTLA-4 that can downregulate immune responses. Blockade of or genetic deficiency in CTLA-4 can result in autoimmunity. Therefore, strategies to increase the inhibitory function of CTLA-4 may be attractive in settings of undesirable T cell responses such as autoimmunity or transplant rejection. We have tested the hypothesis that transgenic constitutive expression of CTLA-4 can further attenuate immune responses when compared with normal inducible expression. Our results indicate that transgenic expression of CTLA-4 in mouse T cells (CTLA-4-Tg T cells) results in reduced cell cycle progression and increased apoptosis of TCR-stimulated T cells. CTLA-4-Tg T cells display reduced T cell proliferation in an in vivo model of graft versus host disease (GVHD). These results further our understanding of how CTLA-4 can be manipulated to inhibit immune responses and may help development of new therapeutic strategies for clinical settings of autoimmunity and transplantation.

Hypocomplementemia is found in all types of membranoproliferative glomerulonephritis (MPGN) but not in all patients. Hypocomplementemia can be ascribed to at least two circulating complement reactive modalities. The activation of the classical pathway produced by circulating immune complexes and the presence in the blood of anticomplement autoantibodies, called 'nephritic factor'(NF). The activation of the classical pathway by circulating immune complexes is probably the major mechanism responsible for hypocomplementemia in idiopathic MPGN type I. Nephritic factors have been shown to be responsible for the hypocomplementemia in both MPGN type II and III. NFa is probably the major mechanism responsible for the hypocomplementemia of idiopathic MPGN type II. NFt appears to be solely responsible for the hypocomplementemia in MPGN type III. Judging from the complement profile, NFt also may be present in some patients with MPGN type I. Although infection by meningococcus has been associated with deficiency of any of the plasmatic proteins of complement, it more commonly involves deficiency of the terminal components of the complement pathway(C5-C9). We experienced a patient who had MPGN and meningococcal meningitis. We examined the complement level and significantly lower levels of C3, C5 were found persistently. C7 was low at first and it returned to normal range after 2 months. C9 was normal at first, and was low after 2 months. This is the first reported case in which MPGN with meningococcal meningitis occurred.

Objective: The effects of maternal and offspring dietary vitamin A (VA) supplementation on early body weight, digestive tract function and immune function in goslings were studied. Methods: Yangzhou geese (180 d old) were randomly divided into 5 experimental groups of 15 females and 3 males (the males were kept until slaughter). Eggs were collected for hatching during the peak laying period. A total of 96 goslings were selected from each treatment group (each fed a basic diet supplemented with 0, 4,000, 8,000, 12,000 or 16,000 IU/kg VA) and randomly divided into 2 groups, with 6 replicates in each group and 8 goslings in each replicate. The gosling diet was supplemented with 0 or 9,000 IU/kg VA. Results: i) Villus length, villus width and the muscle thickness of the duodenum, jejunum and ileum were increased and the crypt depth was reduced after adding 12,000 IU/kg VA to the goslings' diet (p<0.05). Adding 9,000 IU/kg VA to the offspring diet increased the length of the duodenal villi and width of the ileum and decreased the crypt depth of the ileum (p<0.05). ii) Supplementing the maternal diet with 12,000 IU/kg VA increased immune organ weight, the immune organ index and immunoglobulin content in goslings (p<0.05). The bursa weight and immunoglobulin G content of offspring were higher in the 9,000 IU/kg VA supplementation group than in the group with no supplementation (p<0.05). Conclusion: Offspring growth and development were affected by the amount of VA added into maternal diet. The negative effect of maternal VA deficiency on offspring can be compensated by adding VA to the offspring diet. Continued VA supplementation in the offspring diet after excessive VA supplementation in the maternal diet is unfavorable for gosling growth and development.

Objectives : The aim of this study was to investigate the characteristics of Ryodoraku and association of Ryodoraku with gastric dysmotility in functional dyspepsia(FD). Methods : Subjects were 154 patients with FD and 18 patients with asthma. We calculated the average Ryodoraku score(RS, ${\mu}A$) and each variation from physiologic range of 12 Ryodoraku points, and investigated the incidence when left and right points were simultaneously below(bilateral deficiency) or above(bilateral excess) physiologic range. Postprandial regularity of normal slow waves, power ratio, and postprandial % of bowel sound were obtained by electrogastrography and enterotachography, and were used as gastric dysmotility index. Results : 1. Bilateral excess of H4, H5, F1, and F4 and bilateral deficiency of H4, H5, and H6 were characteristic in FD compared with asthma patients. 2. Incidence of gastric dysmotility in bilateral deficiency of H4, H5, and H6 was 100%, and was higher than in total FD patients(88.3%). 3. There was a positive correlation between the variation of H6 and % postprandial bowel sound. 4. Deficient tendency of H4, H5, and H6 was more evident when RS was above $40{\mu}A$ in FD. Conclusions : These findings suggest that gastric dysmotility in FD can be diagnosed when a pattern of H4, H5, H6 bilateral deficiency and F1, F4 bilateral excess is shown at the same time. We think this phenomenon is related to low activity of the vagus nerve rather than meridian pathway with result based on positive correlation between variation of H6 and postprandial % of bowel sound.
