A 2.2 kg adult female Amur leopard cat (Prionailurus bengalensis) injured in a road accident was rescued. Severe abrasions on the left chin were washed daily with an antiseptic and silver sulfadiazine ointment was applied. Corneal edema of the oculus sinister (OS) was treated with ofloxacin and 5% sodium chloride eye drops. The skin wounds gradually improved, but the eye condition did not improve and the lens was also found to be detached. In addition, on the 6th day of hospitalization, melena was observed. On radiographic examination, foreign bodies in the stomach and a fracture of the sternum were confirmed. Subsequently, endoscopic removal of foreign bodies and enucleation of the OS using an electrothermal vessel sealer were performed sequentially over several days. However, corrective surgery of the fractured sternum was not carried out because a natural union of the fracture had occurred, which was found to be fairly stable. The patient completely recovered on the 83rd day and was successfully released into the wild on the 97th day, after two weeks of adaptation training in a natural environment. This report describes the rehabilitation of a wild Amur leopard cat injured in a road accident through a series of diagnostic and treatment steps until its eventual return to the wild and highlights some improvements needed in the process.

Cinnamomum zeylanicum (C. zeylanicum) is a tropical evergreen tree of Lauraceae family. It is one of the oldest culinary spices known and used traditionally in many cultures for centuries. In addition to its culinary uses, cinnamon also possesses as a folk remedy of many health disease condition including analgesic, antiseptic, antispasmodic, aphrodisiac, astringent, carminative, haemostatic, insecticidal, and parasiticide and memory enhancing property. This study was aimed to assess the acetylcholinesterase and butyrylcholinesterase inhibitory activity of standardized methanol extract of the C. zeylanicum. Gas chromatography - mass spectrometry (GC-MS) and high performance liquid chromatography (HPLC) analysis were done to identify the presence of eugenol as chemical component and support the neuroprotective activity in the extract. Anticholinesterase inhibitory activity of crude methanol extract of C. zeylanicum leaves and cinnamon oil were evaluated by 96-well microtiter plate assay and thin layer chromatography bioassay detection methods. This study revealed that cinnamon oil ($IC_{50}:45.88{\pm}1.94{\mu}g/ml$) has better anticholinesterase activity than methanol extract ($IC_{50}:77.78{\pm}0.03{\mu}g/ml$). In HPLC analysis, retention time of eugenol in cinnamon oil was found to be 15.81 min which was comparable with the retention time (15.99 min) of the reference standard, eugenol. Seven chemical compounds were identified by GC-MS analysis, in which eugenol as an important phytoconstituents. Thus the phytochemicals from C. zeylanicum methanol leaves extract could be developed as potential source of anticholinesterase activity, with particular benefit in the symptomatic treatment of Alzheimer's disease.

Content analysis of food advertisements was undertaken to investigate the nature of the messages related to health, nutrition or consumer-promotion in 2001 women's magazines. Advertisements on baby foods were collected from three women's magazines and the final samples obtained were 42 different copies of advertisements. All the messages in each sample were counted and calculated for their frequency (％). Messages were categorized into four areas (health, nutrition, non-nutrition, consumer promotion), and each area was classified into more detailed categories. Results showed that all the messages in 42 samples and average messages per advertisement were 1288 and 30.7, respectively. The most common type of promotional messages was health related (e.g., appeal to enhanced immune function and disease prevention and brain development), followed by consumer related, nutrition and non-nutrition messages in order. Messages about high quality and all natural ingredients were more emphasized in the consumer related category. Messages on fats (DHA, lecithin and arachidonic acid), proteins (neucleotides, taurine) and mineral (calcium, iron) were most frequently found in nutrition category. Amongst the three kinds of baby foods, formula ads had the most numerous messages related to health and nutrition. There were more consumer related messages in the ads of weaning foods, and more promotional messages about no addition of antiseptic, artificial additives, and food colors in the ads for older infant foods. Messages violating regulation (e.g., exaggerated or inaccurate or non-scientific messages) were frequently found in the advertisements of three kinds of baby foods. In conclusion, tighter supervision of food advertisements and nutrition education is required to protect the consumers from misleading advertisements.

Ratanjot is attributed to eight species of Boraginacae species belonging to genera Alkanna, Arnebia, Maharanga and Onosma and regarded as one of the important herbal drugs of indigenous systems of medicine. The root and root stock, which form the actual drug, are considered to be an anthelmintic, antipyretic and antiseptic. They are also claimed to be useful in burn, eczema, wounds and eruptions, and used for treating the diseases of eyes, bronchitis, abdominal pains, itch, etc. Several workers reported that the Naphthaquinones (arnebins), the main active constituents of the drug, are responsible for its colour and therapeutic efficacy. It is claimed that the Arnebia nobilis was imported to India from Afghanistan but the red coloured roots resembling with A. nobilis were found to be gathered by local people for commercial purposes during the course of botanical surey of Himalayan region. Hence, it is decided to evaluate Arnebia nobilis pharmacognostically. The important macro-microscopic features of this species are roots 1-5 cm broad; outermost xylem with broad vessels and innermost with groups of radially arranged narrow vessels while the middle region occupied by alternate rings of clusters of broad and narrow vessels and presence of pith. Besides the percentage of arnebin-1, -3 and 4 are 9.37, 10.53 and 1.72 respectively.

다양한 기능성을 갖는 식물체를 대상으로 새로운 천연 식품보존제 및 방부제 개발의 일환으로 다양한 방법으로 추출한 항균환성 물질을 몇 종의 병원성균과 식중독균, 효모, 곰팡이 등 10개 균주에 대하여 항균활성 검색을 하였다. 각 추출방법에 따른 추출 수율을 보면 편백과 육계 초임계 추출물의 수율이 가장 높았지만, 오레가노와 황금의 경우에는 초임계 추출물의 수율이 가장 낮았다. 그러나 항균활성 실험에서 disc-diffusion method 및 최소억제농도 (MIC) 실험 결과 유기용매 추출 및 열수 추출보다 초임계 추출의 경우가 항균활성이 모든 시료에서 높은 것으로 나타났다. Disc-diffusion method에서 육계 초임계 추출물의 경우 에탄올 추출물보다 항균활성이 두 배정도 높게 나타났고, 10개 균주에 대해 모두 항균활성을 나타냈다. 황금 초임계 추출물은 L. monocytogenes에 강한 항균활성을 보였고, 오레가노와 편백의 초임계 추출물은 S. typhimurium에 강한 항균활성을 보였다. 최소억제농도 (MIC)에서는 편백 초임계 추출물이 다른 초임계 추출물에 비해 강한 항균활성을 보였으며, 그 다음으로 육계, 황금, 오레가노 초임계 추출물의 순으로 항균활성을 나타내었다. 따라서 천연물을 이용한 항균제 개발에 있어 초임계 추출방법이 항균력이 높은 기능성 성분을 추출해 내는데 가장 효과적인 추출방법인 것으로 판단된다.
