OBJECTIVETo provide a new material for producing the Rhodiolasachalinensis products, the effect of methyl jasmonate (MeJA) on callus biomass and effective compound accumulation of Rhodiolasachalinensis was studied.

METHODThe calluses-cultured in 3 L-air lift balloon type bioreactor were treated with MeJA after 20 d of bioreactor culture and the effect of MeJA concentration and treatment days on callus biomass, salidroside or polysaccharide accumulation and superoxide dismutase (SOD) and peroxidase (POD) activities were investigated.

RESULTThe callus biomass was not significantly different after MeJA treatment (125) for 0-6 d but obviously decreased after 6 d treatment. The maximum salidroside or polysaccharide contents and SOD or POD activities were found after 4 d treatment of MeJA. MeJA concentration significantly affected callus biomass and effective compound accumulation, biomass decreased at MeJA concentrations higher than 125 μmol x L(-1). However, the effective compound contents were determined at higher MeJA concentration, and the highest salidroside and polysaccharide accumulation was found at 225 and 275 μmol x L(-1) MeJA, respectively and the maximum SOD and POD activities was found at 225 μmol x L(-1) MeJA. The effective compound contents in callus were compared with field-grown plants. Salidroside contents in calluses were 1.1-fold and 2. 4-fold more than in plant roots and stem or leave, respectively. Polysaccharide content in calluses were 3. 6-fold and 8.0-fold more than in plant roots and stem or leave, respectively.

CONCLUSIONSalidorside and polysaccharide in Rhodiolasachalinensiscalluses improved by MeJA treatment, 225 μmol x L(-1) MeJA and 4 d treatment were optimal. The effective compound contents in callus were obviously higher than in field-grown plants. Therefore, bioreactor culture is efficient for obtaining mass effective compounds of Rhodiolasachalinensis by culturing calluses. This method could provide an alternative material source for production of Rhodiolasachalinensis products.

To improve cell suspension culture system of Panax ginseng, the dynamic of cell growth and medium consumption were studied, and the effects of filter on the culture vessel, revolution number, and inoculation density on cell growth and ginsenoside accumulation were also investigated. The maximum cell growth and ginsenoside accumulation was found on the 20th days of suspension culture, therefore, 20 days were confirmed as a suitable culture period for mass production of ginsenoside. Cell growth and ginsenoside content were promoted when the culture vessel had a ventilated filter. Revolution speed during suspension culture affected cell growth, but not ginsenoside content, a peak of ginsenoside productivity was found in the treatment of 120 r x min(-1). Inoculation density also influenced cell growth and ginsenoside accumulation, inoculation density of 6 g was better than other inoculation densities, the ginsenoside content and productivity were up to 12.8 mg x g(-1) DW and 146.6 mg x L(-1), respectively.

Statement of problem. Primary implant stability has long been identified as a prerequisite to achieve osseointegration. So the application of a simple, clinically applicable noninvasive test to assess implant stability and osseiointegratation are considered highly desirable. Purpose. The purpose of this study was to evaluate the ISQ value and the insertion torque of the 3 different implant system, then to evaluate whether there was a correlation between ISQ value and insertion torque; and to determine whether implant design has an influence on either insertion torque or ISQ value. Material and method. The experiment was composed of 3 groups: depending on the implant fixture design. Group1 was Bra.nemark type parallel implant in 3.75*7mm. Group2 was Oneplant type straight implant in 4.3*8.5mm. Group3 was Oneplant type tapered implant in 4.3*8.5mm. Depending on the density of the bone, 2 types of bone were used in this experiment. Type I bone represented for cortical bone, type II bone represented for cancellous bone. With the insertion of the implant in type I and type II bone, the insertion torque was measured, then the ISQ value was evaluated, and then the correlation between insertion torque and ISQ value was analyzed Result and conclusion. Within the limitations of this study, the following conclusions were drawn. 1. Within the 3 different implants, the insertion torque value and ISQ value were higher in type I bone, when compared with type II bone.(p<0.05) 2. In type I and type II bone, Oneplant type tapered implant has the highest value in insertion torque.(p<0.05) 3. In type I and type II bone, there was no difference in ISQ values among the 3 types of implant. (p>0.05) 4. Significant linear correlation was found in Bra.nemark type parallel implant: 3.75*7mm in type II bone.

BACKGROUND: Although the pathogenesis of vitiligo isn't fully understood, a recent study demonstrates that oxidative stress plays an important role to induce vitiligo. Peroxiredoxin (Prx) is a novel peroxidase family to remove hydrogen peroxide using thioredoxin system, which is consisted of thioredoxin, thioredoxin reductase, and NADPH. OBJECTIVE: This study aimed to investigate the change of expression of Prx I to elucidate the role of oxidative stress in the pathogenesis of vitiligo. METHODS: Sample specimens were obtained from the lesional skin of vitiligo patients, and non-depigmented skin was obtained from the perilesional area as control samples. The skin samples were immediately frozen using liquid nitrogen, and then section samples were prepared to perform immunohistochemical staining with antibodies for Prx I. Some of the skin biopsy samples were used for primary culture of keratinocytes. Protein extracts from the expanded keratinocytes were prepared for Western blot analysis of Prx I. RESULTS: In vitiligo, the ubiquitous expression of Prx I in all layers of epidermis, which was also observed in the normal perilesional skin, was reduced in the depigmented lesion of vitiligo patients. The reduction of Prx I was remarkable from the lesions which were exposed to sunlight. Consistently, Prx I expression from the lesional keratinocytes were noticeably reduced in comparison with that from perilesional keratinocytes. CONCLUSION: Our results showing that Prx I is impaired in the epidermis of depigmented lesions of vitiligo patients suggest that oxidative stress is an important factor to induce vitiligo.

OBJECTIVETo explore the factors affecting the growth of protocorms of Dendrobium candidum and substance synthesis in a reactor, in order to provide a new method for mass production of raw materials of D. candidum.

METHODProtocorms in vitro were used as experimental materials to study the effect of inoculum volume, light intensity and air volume on the growth of protocorms of D. candidum and the accumulation of polysaccharide and dendrobine in a 3 L-air lift balloon type bioreactor.

RESULTAfter 30 days of cultivation in a bioreactor, protocorms became dark green and grew well at the inoculum volume of 10 g x L(-1). The polysaccharide content in protocorms showed no difference at various inoculum volumes; whereas the dendrobine content showed differences (with the highest treatment at the inoculum volume of 10 g x L(-1)), particularly the productions of polysaccharide and alkaloid reached the maximum at the inoculum volume of 10 g x L(-1). The condition of 1 600 lx of light intensity was the most favorable for the growth of protocorms. Though light played a role of improving the accumulation of polysaccharide in protocorms of D. candidum, it could inhibit the accumulation of dendrobine. Polysaccharide content and production were better under light conditions of 1 600 and 2 400 lx than dark conditions. Despite the maximum dendrobine content in dark conditions, the dendrobine production showed the maximum in the light condition of 1 600 lx due to poor growth of protocorms. Protocorms grew well and became dark green at the air volume of 0.2 vvm (air volume culture volume per minute) , which was better than at 0.1 and 0.3, with maximum polysaccharide and dendrobine contents and productions.

CONCLUSIONIn a 3 L-air lift balloon type bioreactor with a working volume of 2 L, the conditions of 10 inoculum volume, 1 600 lx light intensity and 0.2 air volume were favorable for the growth of protocorms and the production of dendrobine. This demonstrates that the cultivation of D. candidum and substance synthesis in a reactor is an effectie approach for mass production of polysaccharide and dendrobine.

OBJECTIVETo cultivate adventitious roots of Hypericum perforatum in bioreactors, in order to seek for suitable conditions for adventitious growth.

METHODThe effect of IBA concentration, sugar type and concentration, inoculum volume and air volume of adventitious roots on the cultivation of adventitious roots of H. perforatum was observed in a 5 L air-lift bioreactor.

RESULTAdventitious roots of H. perforatum were cultivated in a MS culture dish. With the increase of IBA concentration, the propagation coefficient of adventitious roots of H. perforatum was on the rise. The IBA concentration ranging between 1.25-1.75 mg x L(-1) was suitable for the growth of adventitious roots. Adventitious roots grew best with sucrose in MS medium, with the propagation coefficient up to 22.15. When sucrose concentration was 30 g x L(-1), fresh weight, dry weight and propagation coefficient reached the maximum value. An adventitious root reactor with an inoculum volume of 20 g was favorable for the growth of adventitious roots. The air volume of reactors of 0.075 vvm (air volume/culture volume per minute) was favorable for the growth of adventitious roots, with the significant increase in the propagation coefficient of adventitious roots. In the amplification experiment, we found that the cultivation conditions of adventitious roots in a 5 L bioreactor was completely applicable to that in 10 and 20 L bioreactors, and adventitious roots grew well in a large bioreactor.

CONCLUSIONIBA concentration, sugar type and concentration, inoculum volume and air volume had a significant effect on the growth of adventitious roots.
