To observe the regulative effect of applying garlic cream on acupoint Shenque (CV8) on circadian rhythm disorder induced by sleep deprivation.Methods:Twenty healthy adult men were randomly divided into normal group(group A),sleep deprivation group (group B) and treatment group (group C).Subjects in group B and C received 48-hour sleep deprivation,and in the meantime subjects in group C were treated by applying garlic cream on acupoint Shenque(CV8),while subjects in group A received no any treatment,then contents of serum noradrenaline (NA) and 5-hydroxytryptamine (5-HT) were detected.Results:The contents of NA in three groups all appeared typical circadian rhythm(P＜0.01 when group A is compared with group C,and P＜0.05 when group A is compared with group B).The peak value in group A was 158.377 and appeared at 10:56,peak value in group B was 291.529 and appeared at 19:44,peak value in group C was 255.964 and appeared at 17:06.The peak phase in group B shifted more obviously when compared with group A,and the peak phase in group C recovered slightly when compared with group B.The contents of 5-HT in group A showed typical circadian rhythm (P＜0.01) and the circadian rhythms in group B and C disappeared (P＞0.05).the peak value in group A was 196.563 and appeared at about13:10.Conclusion:The application of garlic cream on acupoint Shenque (CV8) Can adjust the disturbed circadian rhythm and accelerate the recovery of circadian rhythm.It is a simple and effective therapeutic method for adjusting circadian rhythm disorder.

In previous studies, we demonstrated 10 types of lymphocytes in lymph nodes, each exhibited a different fluorescent color by our thioflavine staining method. Among them, 4 types were able to differentiate into plasma cells of the same fluorescent colors. In the present study, different types of lymphocytes were demonstrated in human peripheral blood by their different fluorescent colors after thioflavine staining. The lymphocytes from the venous blood of 50 healthy persons were isolated with Ficoll-Conray solution and E-rosette and EAC-rosette tests and fluorescent staining with thioflavine were performed. Most of the lymphocytes in peripheral blood are small ones with nuclei and cytoplasm showing blue fluorescence and the blue fluorescence of the cytoplasm is paler than that of the nuclei. The nuclei in a part of these lymphocytes have distinct boundaries. The nuclei in another part of these lymphocytes are smaller and with indistinct boundaries and indentation on one side and show dim fluorescence. Other lymphocytes show different fluorescence. Some show blue round nuclei with distinct nuclear membrane, and no color of fluorescence in cytoplasm, but with blue white patches on one side of the nuclei. Some show dark blue nuclei and bright blue cytoplasm and others show orange yellow or orange red nuclei and yellow cytoplasm. In addition, lymphocytes of grayish blue or grayish yellow nuclei and bluish green cytoplasm or lymphocytes of yellowish fluorescence may be seen at times. Very few lymphoeytes of orange red nuclei with nearly no cytoplasm may be seen occasionally.The lymphocytes with blue fluorescence and indentation on one side of nucleus, those with blue nuclei and blue white patches in the cytoplasm as well as those with orange yellow nuclei and yellow cytoplasm can form E-rosettes with sheep erythrocytes. They are T cells. The lymphocytes with distinct boundaries of nucleus, small size and blue fluorescence those with dark blue nuclei and bright blue cytoplasm as well as those with orange red nuclei and yellow cytoplasm can form EAC-rosettes with sheep erythrocytes sensitized by specific antibody and complement. They are B cells. The lymphocytes with blue nuclei and blue white patches may transform into lymphocytes with orange yellow nuclei and yellow cytoplasm under ultra-violet light irradiation. The latter are few in number in the blood but may be progressively increased in number on prolonged observation. They belong to Group Ⅲ of lymphocytes and are mainly located in the paracortical thymus-dependent zone of lymph nodes. The sma ller lymphocytes with blue fluorescence and distinct nuclear boundary may transform into lymphocytes with orange red nuclei and yellow cytoplasm, which are also very few in number in the blood and are also progressively increased in number on prolonged observation. They belong to Group Ⅱ of lymphocytes and constitute the main component of lymph nodules in lymph nodes.
