Fully expanded leaf explants were cultured on Murashige and Skoog’s (MS) medium supplemented with thidiazuron (TDZ) (0.5-4.0 mg/l), 6-benzylaminopurine (BAP) (0.5-2.0 mg/l), indole acetic acid (IAA) (2.0 mg/l), gibberlic acid (GA3) (1.0-2.0 mg/l) silver nitrate (AgNO3) (2.0 mg/l) and different carbon sources such as sucrose, fructose and glucose (10%-30%) either individually or in combination to induce adventitious buds and regeneration. The highest percentage (63%) of adventitious bud formation and regeneration (68%) was achieved in the medium containing MS with TDZ (1.0 mg/l), IAA (2.0 mg/l) and AgNO3 (2.0 mg/l). For subsequent regeneration and shoot elongation the MS medium having BAP (1.0 mg/l), GA3 (2.0 mg/l) and AgNO3 (2.0 mg/l) was found to be suitable. Amongst the carbon sources tested, the most suitable carbon source was found to be sucrose (3%) followed by fructose (2%) for adventitious bud formation. Excised in vitro shoots were rooted (60%-80%) in half strength MS medium supplemented with indole-3-butyric acid (1.0 mg/l). The well rooted plantlets were hardened in soil + sand + farm yard manure (FYM) mixture with a success rate of 70%-90%. Since in vitro regeneration is highly genotype-dependent in mulberry, the standardized protocol can be effectively used for further improvement of this leading genotype using biotechnological approaches.展开更多

Methods: 60 cases of benign hyperplasia of prostate patients were evenly randomized into treatment group and control group. Those of treatment group were treated with injection o f "Chuan-Shen-Tong" Injectio (composed of Rhizoma Ligustici Chuanxiong, Rad ix Salviae Miltiorrhizae, etc. for relieving hyperplasis of prostate, 4 mL/acupoin t) into Huiyin (CV 1) and the other 60 cases of control group were treated by oral administration of Hytrin (1 mg/d in the 1 st week and increasing 1 mg/3 d, 4 mg at m ost). After 28 days’ treatment, their therapeutic effects were compared. Result s: After treatment, of each 60 cases in treatment and control groups, 11 (18.3%) and 11 (11.7%) were controlled in their symptoms, 25 (41.7%) and 16 (26.7%) had marked improvement, 18 (30.0%) and 17 (28.3%) had improvement, and 6 (10.0%) an d 20 (33.3%) failed, with the effective rate and the markedly effective rate bei ng 90.0% and 66.7% in the treatment group and 66.7% and 38.3% in the control gro up respectively. The therapeutic effect of treatment group was significantly sup erior to that of control group (P<0.01 and P< 0.05). Conclusion: The therapeutic effect of point-injection of "Chuan-Shen-Tong" for benign hyperplasia of p rostate is better than that of oral administration of Hytrin.展开更多
