Utilizing the ~(125)I-Calmodulin-overlay technique, we have detected calmodulin-binding proteins (CaMBPs) in crude extracts of lymphocytes. The results indicated that appendix (B cell), mesenteric lymph node (T, B cell) and spleen (T, B cell) from rabbit contained 19, 20 and 16 species of CaMBPs respectively. Ten CaMBPs with molecular weight 80, 78, 70, 63,50, 41, 36, 22, 17 and 13.5 K D were present in all lymphocytes detected. Lymphocytes were rich in two kind of CaMBPs with molecular weight 17 and 13.5 K D which bound calmodulin in partial calcium-dependent manner.

Objective To investigate the effects of astragalus membranaceus parenteral solution combined with recombinant human erythropietin (rHuEPO) on erythrocyte immunity function in patients with hemodialysis. Methods Fifty-one patients of chronic renal failure(CRF) with hemodialysis were divided into 2 groups randomly according to whether treated with astragalus membranaceus parenteral solution or not(therapeutic group, was 26 cases and control group was 25 cases). IgG, IgA, IgM, RBC-C3b,RR,RBC-ICR, erythrocyte percentage of CD35 positive and SOD was measured before treatment and 8 weeks after treatment. Results After 8 weeks' treatment, IgG,IgA,IgM levels in therapeutic group and IgG,IgA levels in control group were higher than those before treatment(P < 0.01 ). IgM [ (2.03±0.73 ) g/L ] was higher than that in control group (P< 0.05). RBC-C3B,RR, erythrocyte percentage of CD35 positive and SOD were higher and RBC-ICR was lower than those before treatment in two groups (P < 0.05 ) ;compared with that in control group, RBC-C3b, RR was higher [(10.85±2.31 )% ] and RBC-ICR was lower [(5.34±1.91 )% ] (P < 0.05 ).Conclusion Astragalus membranaceus parenteral solution combined with rHuEPO is superior to improve CRF patients' levels of immune globulin and erythrecyte immunity function.

BACKGROUND: The etiology and pathogenesis of Tourette syndrome(TS)is still unacknowledged, and related studies on the relationship between TS and hypoironemia are unavailable. Since hypoironemia has been found existed in children with TS who showed better outcomes after receiving adjuvant ferralium, thereby this study was designed to investigate the relationship between TS and serum iron.OBJECTIVE: To study the relationship between TS and serum iron.SETTING: At a nursing science department of a university-affiliated hospital, pediatric department of a university affiliated hospital and sectional hospital.PARTICIPANTS: Between June 1997 and December 2000, 45 children with TS received treatment at pediatric clinic of Chenghai sectional people' s hospital, Shantou city, who accorded with the diagnostic standards of the second edition of Chinese Psychopathy Category and Diagnostic Standards,those who were confirmed as brain organic diseases by CT and MIR were excluded.METHODS: Serum iron, hemoglobin and the number of red blood cells were determined in 45 TS children and compared with that in 38 controls.MAIN OUTCOME MEASURES: Difference of the level of serum iron and the incidence of hypoironemia between two groups.RESULTS: The level of serum iron was(12.79 ±0.67) μmol/L in experimental group, obviously lower than(19.26 ± 5.38) μmol/L in control.group( P ＜ 0. 005), the incidence of hypoironemia was 42% significantly higher than13% of control group( P ＜ 0. 005).CONCLUSION: Quite a lot of children with TS have hypoironemia that might be one of the pathogenesis factors, the possible mechanism is, as the result of hypoironemia, decreased activity of monoamine oxidase led to abnormal monoamine neurotransmitter.

Objective To explore the organic and biological contamination in water body of Jin River of Tianjin. Methods Three sections were set up in the upper reaches, middle reaches and lower reaches of Jin River respectively. 6 sampling points were set up in each section of the river. The levels of BOD_5~(20), total count of bacteria, fecal coliform count of the river water were determined. The obtained data were assessed based on GB3838-2002 the National Criterion for Environmental Quality of Surface Water. Results The levels of BOD_5~(20) of river water samples collected from each section of Jin River exceeded the standard ruled by GB3838-2002 Grade V. The levels of fecal coliform count of water samples were between the national standards of Grade Ⅲ and Ⅴ of GB3838-2002. The water samples collected from different sections of Jin River water showed no significant differences in the levels of BOD_5~(20) and fecal coliform count, and significant difference in total count of bacteria. Significantly higher levels of total count of bacteria were observed in water samples collected from upper reaches of Jin River compared with those collected from lower reaches (P

In the isolated rabbit aorta, like verapamil ( Ver ) anisodamine ( Ani ) might inhibit the contraction induced by phenylephrine ( PE ) and high K+ with IC50 value of 120 and 86 ? mol/L, respectively. PE/K+ ratio of IC50 was 1.4 which was less than that of Ver. It showed that although PDC may be more sensitive to Ani than ROC, the difference in sensitivity of Ani on 2 calcium chan- nel are less marked than that of some calcium antagonists. Ani had inhibitory effects on 2 contractile components of serotonin (5-HT ) . Ani and Ver could obviously inhibit post-resting potentiatipn and staircase phenomenon in guinea pig atria. Ani also might inhibit the contraction induced by calcium and shift concentration-response nonparallelly to right on both tissues above.The results suggest that Ani possesses nonspecific calcium antagonistic effect and reduces the tension by affecting PDC and ROC to decrease extracellular calcium influx and inhibiting intracellular calcium release.

Objective To summarize the experiences of reoperations on Ebstein's anomaly. Methods Clinical data of 17 cases of Ebstein's anomaly (6 males and 11 females, aged from 3 to 54 years old, averaged 23) were analyzed retrospectively. All the patients felt short breath and palpitation after exertion, and cyanosis was found in two patients. In the first operation, downwards displaced tricuspid valve leaflet was suspended and atrialized right ventricle was replicated in 14 cases, tricuspid anuloplasty and atrial septal defect were repaired in 2 cases, and tricuspid valve was replaced in 1 case. The interval time between two operations was 1-20 years in an average of 8 years. Before second operation, the cardiac function was NYHA Ⅱ in 6 cases, NYHA Ⅲ in 11 cases. Eight cases received Ebstein's anomaly anatomic correction, including transplanting downward displaced tricuspid valve and excising atrialized right ventricle. Seven cases received tricuspid valve replacement. Two cases received tricuspid valveplasty. All of operations were performed on arrested heart with moderate hypothermic cardiopulmonary bypass. The time of cardiopulmonary bypass was 70-287 (89.3?11.1)min, the time of aorta clamping was 70-287 (64.0?8.6)min. The transesophageal echocardiography was routinely performed before the operations and after the hearts rebeating. Results No case died in hospital, and all the patients were followed up for 1-3 years. Transesophageal echocardiography showed the tricuspid valve was closed well (non-reflow in 9 cases, mild reflow in 1 case) in 10 cases which received Ebstein's anatomic correction and tricuspid valveplasty. The cardiac function states of patients were significantly improved (NYHA Ⅰ-Ⅱ). Conclusion Most of patients with reoperations on Ebstein's anomaly can received anatomic correction. Tricuspid valve replacement is available if the pathology of tricuspid valve is severe.
