Objective During continuous ambulatory peritoneal dialysis (CAPD), the loss of complement factors via the dialysate may cause complement deficiencies. This hypothesis was tested in a group of children treated with CAPD. Design Classical (CH50) and alternative (AP50) complement activity and serum levels of factors C1 q, C3, C4, C3d, B, D, and P in CAPD patients were compared to normal controls and to children with preterminal renal failure. Setting Patients were seen in a university hospital; normal controls were seen in an outpatient clinic of a general hospital. Patients A group of 22 children on CAPD was compared to a normal control group of 44 children and to a group of 12 children with preterminal renal failure with a creatinine clearance below 25 mL/min/1.73 m2. Results CH50, AP50, C3, and B were not significantly different from the control group in both the CAPD and preterminal groups. Factors C1q (p=0.01) and C4, C3d, D, and P (p<0.001) were higher in the CAPD group in comparison to the normal control group. The factors D (p<0.001) and P (p=0.02) were also elevated in the preterminal group. For the measured factors there was no significant difference between the CAPD group and the preterminal group. Conclusions There is no deficiency of complement in children treated with CAPD. High levels of C3d and D can be explained by the reduction of their elimination by the kidney. The increased levels of the other factors are presumably due to increased synthesis in renal failure. This does not seem to be caused by CAPD.

Abstract. Pituitary-testicular function was evaluated in 18 patients with chronic renal failure, 9 treated by maintenance haemodialysis (HD) and 9 by continuous ambulatory peritoneal dialysis (CAPD), and compared with a non-uraemic control group. Serum total testosterone and the free testosterone index were significantly low in both dialysis groups. Basal FSH and LH levels were elevated but this reached significance only with regard to LH. The responses of both FSH and LH to the iv administration of LRH were normal. There was no significant difference between the CAPD and HD groups in any of the hormonal parameters estimated. While CAPD may improve control of some metabolic parameters when compared with HD, it does not improve the function of the pituitary-testicular axis.

Abstract Background: Precocious puberty is the second sexual characteristic of girls before 8 years old. The diagnosis of central precocious puberty (CPP) needs to evaluate ovarian function, and ultrasound examination is an auxiliary means for the evaluation of ovary at present. The serum levels of AMH and INHB might be markers of evaluation of ovary according the former research. We investigated the clinical features, serum sex hormones, serum levels of AMH and INHB in 184 girls with precocious puberty, which provided deeper insight into the clinical significance of AMH and INHB in female precocious puberty. Methods: We evaluated 184 girls with precocious puberty at the Department of Endocrinology of Shanghai Children's Hospital from 2017 to 2021, which was consisted of PT, Tanner stage 2 CPP and Tanner stage 3 CPP. We analysed clinical data from the patients including clinical manifestations, AMH, INHB and other hormone levels, and we analysed AMH and INHB in normal control group either.Results: The PT group (P = 0.031) and Tanner stage 2 CPP group (P = 0.006) exhibited significantly higher AMH level than that in normal control group. AMH level showed no significant difference among PT group, Tanner stage 2 CPP group and Tanner stage 3 CPP group. The Tanner stage 2 CPP group exhibited significantly higher level of INHB than that in Tanner stage 3 CPP group (P = 0.013) and normal control group (P = 0.007). AMH and INHB were positively correlated in the four groups, especially in the PT group (r = 0.694**, P < 0.01). AMH and basal LH were positively correlated in PT group (r = 0.296*, P < 0.01). AMH or INHB showed no correlation with chronical age, bone age, uterine volume, ovarian volume, BMI, E2, SHBG, peak LH, basal FSH, peak FSH, IGF-1 or IGF-BP3. The ROC analysis showed that the AUC of AMH or INHB was relatively low. Conclusions: In this research, the serum AMH and INHB in 184 girls with precocious puberty were analysed. The PT group and Tanner stage 2 CPP group exhibited significantly higher AMH level than that in normal control group. The Tanner stage 2 CPP group exhibited significantly higher level of INHB than that in Tanner stage 3 CPP group and normal control group. AMH and INHB were positively correlated in the four groups, especially in the PT group. ROC analysis showed that the diagnostic performance of PT or CPP using AMH or INHB was weak.

Abstract Von Willebrand disease (VWD) is caused by quantitative (types 1 and 3) and qualitative (type 2) defects in von Willebrand factor (VWF). The TS Zimmerman Program for the Molecular and Clinical Biology of VWD is a multinational Program Project established to further the study of VWD in the United States and to contrast these studies with the studies initiated previously in the EU and Canada. As one of the components of this study we sought further insight into the clinical expression and penetrance of established types of VWD by performing full gene DNA sequence analysis in VWD patients and normal controls. This report is an interim report of the first 50 index cases and 113 normal individuals recruited into this study. Twenty four of these index cases were found to have known mutations, four of which had a second new mutation, and 11 cases had 1 or 2 new mutations. In cases where mutations were identified, 46% of the identified mutations were new mutations that have not been reported in the Sheffield VWF Mutation Database. In 15 patients, no mutations were identified in the coding region, although analysis of the non-coding regions is still in progress. Five of the mutations were deletions, insertions, or nonsense mutations that have clear functional consequences. The other 12 mutations were missense mutations. Since VWF polymorphisms are not well characterized in all exons, we have also completed studies of the first 113 normal control individuals in our study. These are individuals without a bleeding history and in whom full VWF laboratory testing and VWF sequencing was also undertaken. Since some estimates in the EU and Canadian studies have determined the prevalence of VWF mutations varies by the severity of type 1 VWD patients, we wanted to determine the frequency of VWF variation in a normal population and determine if sequence variations correlate with VWF levels. There were three linked common polymorphims identified in normal African Americans that are discussed elsewhere and are not included in this present analysis. We found 19 new sequence variations in the normal control group of which three (2900G>A, 6554G>A, 7997C>T) were found individually in 4–6% of the normal control samples. In addition, in 12 normal control samples we identified 6 sequence variations that were previously reported as VWF mutations. Four were reported as type 1 mutations (2220 G>A, 3686T>G, 3692A>C, 6859C>T) and two as type 2N mutations (2451T>A, 2771G>A). The 2220G>A and 2451T>A mutations were seen in 6 normal controls (5%) and 5 of these 6 normal controls had both mutations. In another normal control, both 3686T>G and 3692A>C were identified. Although the reported prevalence of VWD is 1% or greater, the frequency of these mutations in our normal controls is higher than expected (as high as 5%). In our normal control group, the mean VWF:Ag concentration in the patients with polymorphisms/mutations did not differ from the normal control group as a whole and did not cluster on the lower end of the normal range. Thus, the data on our normal individuals suggest that VWF gene variation is considerable and that many mutations and polymorphisms remain to be identified. Differentiation of those that affect the diagnosis of VWD and/or hemorrhagic risk continues to be difficult.

The nasal cycle in patients with septal deviation was studied by acoustic rhinometric techniques. This study included 24 patients with anteriorly located septal deviations (mean age = 23.5), and 26 normal controls (mean age = 24.7). Data of MCA (minimum cross-sectional area) and NV (nasal volume), collected in 20-minute intervals, were plotted for each subject during 8 hours. Twenty of 24 patients (83%) with septal deviation and 20 of 26 normal subjects (77%) showed at least one complete cycle. Duration of the nasal cycle, which ranged from 100 minutes to 400 minutes, had no statistical difference between the septal deviation group (mean duration of 216 minutes) and the normal control group (mean duration of 227 minutes). The degrees of variation of MCA and NV, defined as Degree of Variation of MCA (%) = 100 (MCAmax – MCAmin)/MCAmax, Degree of Variation of NV (%) = 100 (NVmax – NVmin)/NVmax, which represent the percent change of MCA and NV throughout the study, showed no difference between the wide side and the narrow side, or between the septal deviation group and the normal control group. These findings suggest that the nasal cycle is relatively independent of peripheral anatomic factors for its generation. However, the amplitude of changes of MCA was greater in the wide side, and the sum of both MCAs tended to fluctuate in accordance with the fluctuation of MCA of the wide side. Thus, the nasal cycle seemed to be affected by septal deviation.

Male infertility has occurred rapidly in the last few decades, primarily in developing countries. An antioxidant, hesperetin is a flavonoid that is found in abundance in orange peels. The aims of this research were to determine the effect of hesperetin on blood sugar levels, spermatozoaquality, and spermatozoa quantity. The research structure included induction of diabetes mellitus and treatment for 8 weeks, followed bydetermination of blood sugar levels, spermatozoa quality, and spermatozoa quantity. Hesperetin has the ability to restore blood sugar levels, spermatozoa quantity, seminiferous tubules diameter, and testicular weight, volume, and germinal epithelial layer thickness with significant difference from the normal control group. Hesperetin did not fully restore spermatozoa motility, viability, and morphology with significant difference from the normal control group, nor from the positive control group. However, overall, hesperetin decreased blood glucose levels, increased spermatozoa quantity, and improved the spermatozoa quality in alloxan-induced diabetes mellitus mice. Dose-dependent activity was observed with the optimum dose at 200 mg/kg body weight.

The experiment was conducted on 90 adult healthy Wistar rats. Rats were randomly divided in to 15 equal groups, each of 6 rats, and were kept in separate cages. Group I served as normal healthy control without any treatment, while Group II and III served as vehicle (bicarbonate) control and lithiatic control, respectively. In rats of Group III to IX urolithiasis was induced using 0.75 % (v/v) ethylene glycol and 2% (w/v) ammonium chloride in drinking water for 28 days. The rats of Group I, II, and X to XV were given pure wholesome water till 28 days. After 28th day, the rats of urolithiatic treatment Groups IV, V, VI, VII, VIII and IX were given aqueous and alcoholic extracts of Bryophyllum calycium and Solanum xanthocarpum @ 300 mg/kg bwt orally as either single extract or combination as biherbal extracts in 0.5 % sodium bicarbonate using syringe and rat lavage needle, and so also was done for rats of Group X to XV as extract control groups. Blood samples were collected twice: i.e. on day 28 of induction of urolithiasis and then on day 56 of experiment from all rats. No significant difference was observed in any of the haematological parameters and even in serum albumin and globulin levels before and after treatment in different groups. However, increased levels of serum BUN, uric acid and creatinine were observed in the urolithiatic groups as compared to the normal control group on 28th day. While serum total protein levels were decreased in the calculi induced groups as compared to the normal control group. However, co-treatment of aqueous or alcoholic extract of Bryophyllum calycinum and Solanum xanthocarpum significantly restored these changes by 56th day. The effect of biherbal alcoholic extract of the plants was much better in restoring the values and the levels came nearer to normal by 56th day of oral treatment proving nephroprotective effect of these extracts.

Activity of acid phosphatase (AP), beta-glucuronidase (GR), N-acetyl-beta-D-glucosaminidase (GZ), and peroxidase (P) was assessed using a semiquantitative cytochemical method in peritoneal macro phages of 30 patients with end-stage renal failure treated by intermittent peritoneal dialysis and of 30 control patients with normal renal function. The dialysed patients showed a significantly higher activity of GR and P at the beginning of the treatment as compared with the respective activities observed in the control group and a further significant rise of these activities after 4 months of dialysis. Activity of AP at the beginning of the treatment was insignificantly lower than in the control group and the difference became significant at the end of the investigated period. There was no significant difference between the dialysed patients and the control group in the activity of GZ assessed at the beginning of the dialytic treatment and after 4 months of dialysis. A significant decrease in that activity was, however, observed in the course of dialysis.

The objective of this study was to investigate histopathology of livers and carry out body weight determination in normal rats administered with  tamsulosin. Standard methods and procedures were used in this study. The results were revealed. Pertaining weight, at the 3rd , 6th and 8th weeks of the study, no significant difference (P>0.05) in weight was found in the group of rats treated with carvedilol (positive control), tamsulosin low dose (12μg/kg) and high dose tamsulosin (40μg/kg) compared to normal control group, respectively. Other inter-groups comparisons were not significantly different, respectively. Pertaining liver morphology, liver sections of groups revealed no significant histological lesions compared to the normal control group at the 6th and 8th weeks of the study, respectively. This study revealed that the tamsulosin cause no histopathological lesion, thus the drug might be safe to the liver and its biochemical processes.

The Carrow Elicited Language Inventory was used to compare the imitation skills of kindergarten children identified as high risk for learning disability with those of a normal control group. A significant difference was found between the two groups in the total number of errors. Differences were also found in the ability to imitate adjectives, conjunctions, pronouns, and verbs. An incidental finding, failure on the part of many high-risk subjects to imitate interrogative stimuli, is discussed in terms of a processing deficit.

Abstract Introduction Along with clinical assessment, D-dimer (D-d) assays are routinely used to exclude DVT. It has been suggested that measurement of derived fibrinogen (DF) may be an effective reflection of endogenously-derived thrombin generation and that ratios between this and Clauss-derived fibrinogen (CF) may be useful in determining whether patients have experienced, or are vulnerable to thromboembolic events. Some studies indicate that a D-d/fibrinogen ratio is significantly higher among patients with confirmed DVT. The purpose of this study was to determine whether DF/CF ratios in individuals are a useful adjunct to D-d assays in the detection of DVT compared to D-d assay in isolation. Methods Venous samples were collected into glass B-D Vacutainers containing tri-sodium citrate (Becton-Dickinson, Plymouth, UKRef: 367691) from 162 out-patients presenting to the medical admissions unit with suspected DVT. Laboratory staff (N=100) served as the normal control group. D-dimer (MiniVidas, BioMerieux), DF and CF (Dade-Behring reagents in combination with a CA1500 coagulometer) were measured on all patients and normal control samples within two hours of collection. Results Following clinical assessment (Wells scoring), 85 patients were considered not to have had a DVT. Doppler scanning confirmed DVT in 38 of the remaining patients and 39 were shown to be negative. Two sample t-test analysis of the data showed significant differences between DF and CF levels in the normal group (n=100), patients who did not have a DVT (n=124) and those who did have a DVT (n=38), (p = &lt;0.05 in each group). There was a significant difference in the DF/CF ratios between the three groups (p = 0.014, one-way ANOVA). The mean DF/CF ratios in the normal control group, patient negative group and patient positive group were 1.16, 1.22 and 1.24 respectively. There was no overall correlation between D-d and DF (correlation co-efficient = 0.646), D-d and CF (correlation co-efficient = 0.581) nor between D-d and DF/CF. Of the DVT positive patients, 26 had a raised DF whereas only 12 had a raised CF. Conclusion Our data suggest that DF/CF ratios cannot be used as an adjunctive marker of DVT when used in combination with D-d values. DF/CF ratios are significantly higher in patients attending for clinical assessment irrespective of whether they are DVT positive or DVT negative. This may be because fibrinogen is an acute phase protein which increases with various pathological states and stressful events such as the experience of attending hospital for investigation and assessment. Further work is required to determine whether DF/CF ratios can be used adjunctively when the D-d cut off value is significantly higher than that used conventionally.
