A study on various symptoms of chronic hepatitis treated with radix astragali and its regulative effect to levels of serum hormone

Sixty-seven cases of chronic hepatitis were treated with Radix Astragali. After treatment (2-month course), the clinical improvement rate in 38 cases of the Stagnation of the Liver-Qi and Deficiency of the Spleen type was 92.1%, and in 26 cases of the Deficiency of Liver Yin and Kidney Yin type was 88.5%, more effective than in the control group (P<0.05). The regulative effect to the levels of serum hormone was observed in the patients of the Stagnation of the Liver-Qi and Deficiency of the Spleen type treated with this medicine. The results showed that the levels of serum triiodothyronine, estradiol (female) and testosterone (male) were increased after treatment (1.40±1.38 ng/dl, 129.30±1.23 pg/ml and 496.24±1.47 ng/dl). Pre-treatment levels were 1.22±1.49 ng/dl, 104.60±1.45 pg/ml and 398. 17±1.55 ng/dl respectively (P<0.05); however, the level of serum prolactin (2.75±4.46 ng/ml) was lower after treatment than before treatment (3.20±3.82 ng/ml,P<0.05). No obvious changes were observed in the levels of serum follicle stimulating hormone, luteinizing hormone, thyroid stimulating hormone, thyroxine, triiodothyronine uptake ratio and cortisol after treatment.     

Sexual abuse of children: an area with room for professional reforms

The cases of 46 children who had been abused sexually an average of 2.6 years previously, were reviewed and the non-offending parents were interviewed with emphasis on how they viewed the professional persons who had seen their children, and their opinions of the legal processes that were instituted. The parents found most professional groups helpful, with officers from the Department of Youth and Community Services being seen as the least helpful. Twenty-one of the cases went to court; in 12 cases this resulted in a conviction, and prison sentences were imposed on six of the offenders. Children found the court experience distressing and most parents expressed dissatisfaction with the outcome of the court hearing. Children were more likely to be required to give evidence in court if the offender had legal representation. Persisting behavioural problems and poor school performance were more likely to occur in those cases in which there had been court hearings. A review of Police Department records of children who had attended the hospital for the management of sexual assault, showed that 10 of the 107 children who are now aged over 14 years, have themselves been convicted of violent crimes since their episode of sexual assault. Long-term intervention is required to help many of these children, some legal reforms are necessary to reduce the stress that they experience when there is a court hearing, and all the professional groups that are likely to become involved with the problem of the sexual abuse of children need to be better informed about its seriousness and consequences.     

Correlation between the intensity of cytomegalovirus infection and the amount of perivasculitis in aortic allografts

Abstract  We previously demonstrated that cytomegalovirus (CMV) infection enhanced perivascular inflammation in rat aortic allografts. In this study, we investigated the relationship between the CMV infection load and the magnitude of perivasculitis (chronic rejection) in aortic transplants. Rats received or-thotopic abdominal aortic grafts, different degrees of total body irradiation (TBI) for immunosuppres-sion and CMV inoculation. The spleens of the rats receiving 5 Gy of TBI contained more infectious virus and viral antigens than those of rats receiving 3 Gy of TBI or no TBI. Although the number of inflammatory cells infiltrating the perivascular area was decreased after TBI, CMV infection resulted in increased perivasculitis in rats that received 5 Gy of TBI as compared to non-infected animals. This virus-induced effect was characterized predominantly by an increased T-cell infiltration, including CD4 and CD8 T-cells. It is concluded that an enhanced systemic CMV infection during severe immunosuppressive therapy can accelerate the development of chronic rejection, which seems to be mediated mainly by T-cells.

Controlled-release codeine is equivalent to acetaminophen plus codeine for post-cholecystectomy analgesia

PURPOSE: Following ambulatory surgery, long-acting analgesics may provide advantages over short-acting analgesics. This study compared controlled-release codeine (CC) and acetaminophen plus codeine (A/C; 300 mg/30 mg) for pain control in the 48-hr period following laparoscopic cholecystectomy. METHODS: Eligible patients were randomized to CC or A/C in a double-blind, double-dummy parallel group study. Unrelieved pain in hospital was treated with fentanyl i.v. bolus. Pain [100 mm visual analogue scale (VAS)] was assessed before the first dose of medication; at 0.5, one, two, three, and four hours post-dose; at discharge; and three times a day for 48 hr. Adverse events were recorded and measures of patient satisfaction were assessed at the end of the study. RESULTS: Eighty-four patients were enrolled in the study; 42 patients in each group. There were no statistically significant differences between CC and A/C treatment. Mean VAS baseline pain was similar in both groups (P = 0.49) and there was no significant difference in the time to onset of analgesia (P = 0.17). At 0.5 hr, the mean VAS pain score was significantly reduced from baseline in both groups (P = 0.0001). The VAS pain scores at discharge were reduced 59% and 56% from baseline, respectively (P = 0.61). There was no difference between treatments in the incidence of adverse events and patients reported similar levels of satisfaction. CONCLUSIONS: Controlled-release codeine provides an equivalent onset of analgesia, reduction in postoperative pain, and level of patient satisfaction, to acetaminophen plus codeine, over 48 hr following cholecystectomy, with the advantage of less frequent dosing.

Extracorporeal shock wave lithotripsy for difficulty in withdrawal of double J ureteral stents due to ureteral lithiasis.

OBJECTIVE: To explore the efficacy of extracorporeal shock wave lithotripsy (ESWL) to coping with lithiasis-induced difficulty in withdrawing double J ureteral stents. METHODS: This study includes 6 patients with difficulty in withdrawing the stents due to lithiasis, who were in the anterior prone position or posterior oblique supine position to receive ESWL treatment. The stones were localized by double-band intersection X-ray system. The treatment voltage of shock wave was 11.2 kV initially, which was gradually increased to 18.1 kV, and the shock wave attack amounted to 1,000 to 3,000 times in total. RESULTS AND CONCLUSION: After ESWL treatment, the encrusted double J stents were successfully withdrawn in all the 6 cases, without causing any morbidity related to the use of ESWL. Among the various techniques available for removing encrusted double J stents, ESWL appears to be the most effective and the least invasive modality.
