  • There is a need to develop diverse cultivation species with reference to the favorites and farming experiences of allotment garden participants, in addition to the crops being cultivated in the gardens. In this study, therefore, a survey on the status of cultivation and the demand for herb crops for the garden participants was conducted. Current trend of the programmes related to allotment garden for city dwellers, executed by various relevant organizations was analyzed. A questionnaire was accomplished by adult participants experiencing farming in allotments. Likewise, interview with farm proprietors was conducted. The results showed that the number of crop species cultivated in allotments was about ten species. The purchase of seeds and nursery plants was mainly dependent on the farmland proprietors. The selection of the crops was made by both wife and husband. The status of herb utilization indicated that 5.7% of participants were cultivating or had cultivated herb plants. Sixty-two percent of participants were not cultivating herb plants because they did not know how. The purposes of using herbs were for medicine and beauty (22.0%), for spices (22.0%) and for enjoyment (29.0%). Thirty-four percent (34.0%) of participants were interested or would like to use the herbs in the future for medicine and beauty, 39.0% for spices and 31.7% for enjoyment. It is expected that the demand for herbs would increase. Also, 78.3% of participants had the intension or had taken into consideration to cultivate the herb plants, if the farmland proprietors would provide the plants. And, they had interest in planting, management and post harvest utilization and if a reference material would be provided as well. An approach to plant new crops might be possible to those who have more than four years of farming experience and possess relatively high level of cultivation techniques. In conclusion, the favorable crop cultivation strategy corresponding to the participants' abilities; and rental process were essential for the sustainable operation of allotment gardens and expanded number of participants. Moreover, there is a need to pay attention to the city dwellers who have a lot of farming experiences in allotment gardens to maintain agriculture and rural community. This is so, because they are interested in agriculture and rural community and most of them replied that they had intentions to move to rural areas in the future.

  • Severe wilt disease epidemic was found on winter daphnes (Daphne odora Thunb.) cultivated in farmers, nurseries in Suncheon, Jeonnam in 2003. Typical symptoms appeared on the leaves of winter daphne as yellowish wilts and turned brown from the lower leaves on the same plant. Severely infected leaves were defoliated, resulting in blight of stems and eventual death of the entire plant. Black decayed vascular tissues were distinctly observed in a wilted plant. Fusarium sp. was isolated from the diseased plants repeatedly and its pathogenicity was confirmed by artificial inoculation on healthy plants. The fungus was identified as Fusarium oxysporum on the basis of the morphological and cultural characteristics on potato dextrose agar and carnation leaf agar. The optimum temperature for fungal growth was around $25{\circ}C$ and the fungal growth was inhibited by metconazole, triflumizole and trifloxystrobin on potato dextrose agar. This is the first report on the wilt disease of winter daphnes caused by F.oxysporum in Korea.

  • During the past two decades, China has seen her great progress in plant biotechnology. Since the Chinese market of herb medicine is huge, while the plant resources are shrinking, particular emphasis has been placed in plant tissue and cell cultures of medicinal plants, this includes fast propagation, protoplast isolation and regeneration, cell suspension cultures and large scale fermentation. To optimize culture conditions for producing secondary compounds in vitro, various media, additives and elicitors have been tested. Successful examples of large scale culture for the secondary metabolite biosynthesis are quite limited : Lithospermum ery throrhizon and Arnebia euchroma for shikonin derivatives, Panax ginseng, P. notoginseng, P. quinquefolium for saponins, and a few other medicinal plants. Recent development of genetic transformation systems of plant cells offered a new approach to in vitro production of secondary compounds. Hairy root induction and cultures, by using Ri-plasmid, have been reported from a number of medicinal plant species, such as Artemisia annua that produces little artemisinin in normal cultured cells, and from Glycyrrhiza uralensis. In the coming five years, Chinese scientists will continue their work on large scale cell cultures of a few of selected plant species, including Taxus spp. and A. annua, for the production of secondary metabolites with medicinal interests, one or two groups of scientists will be engaged in molecular cloning of the key enzymes in plant secondary metabolism.

  • This study has been geared to document primary information on common complementary and alternative medicines (CAM) used to treat and/or manage common dermatological disorders in Mauritius, a tropical multicultural island in the Indian Ocean. Data from 355 key informants was collected via a semi-structured questionnaire. Pearson correlation and Chi-squared test were performed to delineate any association. Quantitative indexes including the Importance Value (IV) and fidelity value were calculated. Results tend to indicate that cultural reasons were behind the use of CAM among Mauritians and traditional knowledge was mainly acquired either from parents/relatives or from self-experience. Among the medicinal plants mentioned, Aziadiracta indica (IV = 0.78) and Paederia tomentosa (IV = 0.70) were found to be most used plants. Calendula officinalis (IV = 0.15), Centella asiatica (IV = 0.22) and Agauria salicifolia (IV = 0.11) were also recorded to be used for common dermatological disorders though greatly under-utilised. Animal products were mentioned by 38.0% respondents and cow ghee was found to be commonly used in the management of measles (IV = 0.88). Spiritual healing was found to be used mainly for measles and warts. Given the plethora of novel information documented from the present survey, it can be suggested that the Mauritian population still relies to a great extent on CAM which needs to be preserved and used sustainably. Nonetheless, further investigation is required to probe the possible active constituents that could be the basis of an evidence based investigation to discover new drugs.

  • Aldose reductase (AR) has been reported to play an important role in sugar-induced cataract. In the present study, the AR inhibitory activity of Enicostemma hyssopifolium (EH), Gymnema sylvestre, Eclipta alba, and Tinospora cordifolia (TC) were studied along with their effect on sugar-induced cataractogenic changes in sheep lenses in vitro. AR inhibitory activity of the aqueous extracts of plants and their anticataract potentials were evaluated in vitro in sheep lenses, considering the activity of normal sheep lenses as 100%. The concentration of the plant extract that showed maximum activity was selected to further study its effect on galactose-induced polyol accumulation in vitro. The $IC_50$ values of EH and TC were calculated to be 102 and 85 ${\mu}g$/ml, respectively. EH showed a significant inhibition (61.3%) in polyol accumulation followed by TC (53.1%). EH and TC possesses a significant anticataract activity in vitro and its anticataract potential could be related with its AR inhibitory effect.

  • The whole plants of Selaginella tamariscina, Orostachycis japonicus, the cortex of Ulmus mandshurica, and the wood of Alnus japonica have been used as folk medicine for treating cancer. The cytotoxic activity of these plants were tested using a calorimetric tetrazolium assay (MTT assay). S. tamariscina and A. japonica showed mild $IC_{50}$ value, comparing with O. japonicus and U. mandshurica. So, MeOH extracts of S. tamariscina and A. japonica were partitioned into $CHCl_3$, EtOAc and n-BuOH, successively. The $CHCl_3$, EtOAc and BuOH fractions of S. tamariscina and A. japonica showed low percent of survival against $P_{388}$ and $MKN_{45}$ cells respectively. To isolate active components, they were subjected to silica gel column chromatography. Compound I was obtained from EtOAc extracts of S. tamariscina and identified as amentoflavone by chemical and spectral analysis. Amentoflavone inhibited the survival of P388 cells dose dependently, while not clearly inhibited that of $MKN_{45}$ cells.

  • Many plant species are used in Malaysia in folk medicine for the treatment of cancer. This paper presents some of these species with details on other ethnopharmacological uses, the known bioactivities and some chemical constituents of each of the species given. It is normal practice in traditional medicine that one species of plant is used to treat various ailments. Thus the plant species listed are all used to treat cancer but have various other ethnophrmacological uses as well, some with few other uses and rest with many other uses. Information on bioactivities of each species resulting from tests on human and experimental animals are also given. Proven bioactivities give strength to ethnopharmacological claims on the efficacies of plant resources in the treatment of cancer and various other ailments but will but will not necessarily lead to the production of new pharmaceutical drugs. Many of the known chemical constituents of each species are given. This shows the richness and variety of chemicals containes in each of the species listed, The chemicals listed may or may not prove to be important in the pharmaceutical sciences but is an indication of what each species contatin in thrms of plant chemicals, It is a well known fact that many of the pharmaceutical prescriptions in present day use are of plant origin and semi-synthetic or fully synthetic chemicals produced using knowledge gained from studies of phytochemicals. Thus the paper presented will give useful information and also shows the richness of plant species that have high potentials for the development of anti-cancer resources from plants in Malaysia.

  • This study was carried out to understand the contamination patterns of Listeria in pork processing plants. A total of 402 samples were collected from carcass, pork during processing, surfaces of equipment and environment, and 238 isolates of Listeria species were identified. L. innocua was found in 64.7% of the isolates, L. monocytogenes in 33.2%, and L. welshimeri in 2.1%. Random amplified polymorphic DNA (RAPD) analysis performed to investigate the origin and routes of Listeria contamination, showed 21 composite types of L. monocytogenes and 26 composite types of L. innocua. It was confirmed that Listeria contamination begins with contaminated incoming carcass and ever-present contaminants in the processing environments. The persistence and dissemination of the same strain of L. monocytogenes and L. innocua throughout the processing line revealed that the sanitation standard operating procedure should be implemented to minimize the risk of colonization in the workplace. Molecular subtyping of L. innocua allowed us to tracing the possibility of cross-contamination during processing.

  • Water extract (kwath) of six different widely used Ayurvedic medicinal plants were tested in mice for possible neuropharmacological efficacy. In the present experiments it was observed that a number of plant tested causes a significant level of Central Nervous System (CNS) depression, in that it significantly decreased the spontaneous Motor activity, and also lowered the exploratory behavior of the treated animals. Terminalia chebula (HAA), Terminalia bellerica (BHA), Emblica officinalis (AA), Piper longum 1. (PP). exhibited depressant action of on the CNS. Apart from them a mild to moderate degree of depression was evident as a consequence of administration of Zingiber officinale Rosc (SUT), Piper nigrum L. (MRC). However, none of the plant tested did not exhibit significant effects on pentobarbital induced narcosis, and this indicated that the sedating effects of the drug was not associated with the risk of fatal consequences on overdose.
