[A KABP (knowledge, attitude, belief and behavior) study about AIDS among taxi drivers and hotel attendants in Beijing]

This article reports the KABP study on 448 taxi drivers and 556 hotel attendants in Beijing for the first time in China. A self-administered questionnaire was used to investigate knowledge, attitude, belief and practice (KABP) about AIDS. In terms of knowledge, 23.8% of hotel attendants and 36.8% of taxi drivers did not know that contact with blood could transmit HIV. Thirtyfive percent of hotel attendants and 42.2% of taxi drivers did not believe that intravenous drug users were at high risk. Some drivers (13.6%) and hotel attendants (3.4%) reported having multiple sexual partners. Forty-one point nine percent of taxi drivers and 16.6% of hotel attendants preferred the idea of multiple sexual partners. Among hotel attendants, a negative association was found between knowledge about AIDS and multiple sexual behavior (P < 0.01). Regarding attitude toward condom use, 56.2% of taxi drivers and 47.8% of hotel attendants who have had a sexual experience thought that condom use interfered with sexual pleasure. Seventy-six point eight percent of taxi drivers and 79.8% of hotel attendants believed that they could change their behaviors in order to minimize the chances of getting HIV. This study indicates that HIV education is important in reducing the number of sexual partners and promoting the use of safe sex practices like condom use. Furthermore, as reported by the study population, education can change behavior.

Selective inhibition by magnosalin and magnoshinin, compounds from "Shin-i" (Flos magnoliae), of adjuvant-induced angiogenesis and granuloma formation in the mouse pouch

Inhibitory effects of magnosalin and magnoshinin, compounds from the crude drug "Shin-i" (Flos magnoliae), on angiogenesis and pouch granuloma formation in mice induced by an adjuvant containing croton oil were investigated. The anti-chronic inflammatory effect of "shin-i" was caused by selective inhibition of angiogenesis by magnosalin and of granuloma formation by magnoshinin.

[Treatment and analysis of 54 cases of vulval carcinoma]

Fifty-four cases of vulval carcinoma are reported. The over all 5-year survival rate was 87%. In 32 cases treated by surgery alone and in 15 cases who had combination therapies, the 5-year survival rate was 84% and 80% respectively. The extent of operation was discussed. Continued adjuvant therapies should be given in patients at high risk of recurrence.

Selective inhibition by magnosalin and magnoshinin, compounds from 'shin-i' (Flos magnoliae), of adjuvant-induced angiogenesis and granuloma formation in the mouse pouch

Inhibitory effects of magnosalin and magnoshinin, compounds from the crude drug 'Shin-i' (Flos magnoliae), on angiogenesis and pouch granuloma formation induced by an adjuvant containing croton oil were investigated. Magnosalin inhibited angiogenesis 2.4-fold (intra-pouch) and 9.7-fold (intraperitoneal) more strongly than granuloma formation. The inhibition of angiogenesis by magnosalin was 5-fold (intra-pouch) and 21-fold (intraperitoneal) weaker than that by hydrocortisone. In contrast, intraperitoneal magnoshinin inhibited granuloma formation 2.5-fold more strongly than angiogenesis. The regression coefficients of anti-angiogenesis vs. the inhibition of granuloma formation were 1.79 for magnosalin, 1.11 for hydrocortisone, and 0.61 for magnoshinin. These results show that the anti-chronic inflammatory effect of 'Shin-i' was caused by selective inhibition of angiogenesis by magnosalin and of granuloma formation by magnoshinin.
