Melissa parviflora Benth. is an aromatic perennial herb of Lamiaceae family. It is one of the most influencial plant and used from centuries in Unani system of medicine for the treatment of various malady such as Epilepsy (mirgi), hemiplegia (falij), migraine (shaqeeqa), insomnia (sehar), indigestion (sue hazm) and palpitation (khafqaan) etc. The Persian physician Avicenna endorsed it for heart problems. It has antitubercular, antipyretic, analgesic and stomachic properties, also used to remove bad breath from mouth, strengthen the gums but its main action is as a tranquillizer and nervine relaxant, it is greatly esteemed for its calming properties. Preliminary performed phytochemical analysis revealed that tannin, flavonoid and saponins are the major components of the plant extract. The plants containing saponins or flavonoids exhibit anticonvulsant activity whereas the flavonoids show various biological activities including antioxidant, anti-inflammatory and cytotoxic-antitumor etc. Keeping in view the tremendous medicinal importance of the plant Badranjboya in Unani Medicine, this review provides updated information on its phytochemistry, therapeutic uses and pharmacological properties.

Lycii Radicis Cortex, the root bark of Lycium chinense Miller (Solanaceae) is used in oriental medicine as a tonic and is reported to exhibit hypotensive, hypoglycemic, and antipyretic activity. Recently, we have isolated dihydro-N-caffeoyltyramine, a phenolic amide, from the Lycii Radicis Cortex. Treatment with dihydro-N-caffeoyltyramine significantly inhibited the proliferation of human leukemia cell lines HL-60 in a dose-dependent manner. We found also that the growth inhibition of HL-60 by dihydro-N-caffeoyltyramine is associated with induction of apoptosis of cells. (omitted)

Salicylamide, a non-steroidal anti-inflammatory drug (NSAID), is used as an analgesic and antipyretic agent. We have previously shown that several NSAIDs have anti-melanogenic properties in B16F1 melanoma cells. In contrast, we have found that salicylamide enhances melanin contents in B16F1 melanoma cells; however, the underlying mechanism is not known. Therefore, we investigated the mechanism through which salicylamide stimulates melanogenesis. Interestingly, salicylamide enhanced diphenolase activity in a cell-free assay. Western blotting and real-time RT-PCR revealed that salicylamide increased tyrosinase expression via transcriptional activation of the Mitf gene. Together, our results indicate that salicylamide could be used as an anti-hypopigmentation agent for skin and/or hair.

For microbial production of acetaminophen, a popular analgesic-antipyretic from aniline, we screened various fungi and bacteria. And we succeeded to some extents in acetaminophen production by successful protoplast fusion between S. lividans and S. globisporus and also between S. rimosus and S. aureofaciens. However, more fertile results might be brought via performing the cloning of acetanilide p-hydroxylation genes of Streptomyces in yeast. This study was initiated to determine whether the acetanilide p-hydroxylase of Streptomyces is cytochrome P-450 species or non-heme iron protein species. The p-hydroxylationactivity on acetanilide in S. aureofaciens ATCC 10762 was found to be unstable on exposing to the air. However, 100,000xg supernatant of the cell free extracts which were prepared in $N_2$ atmosphere showed the p-hydroxylation activity. Characteristic absorption peak of cytochrome P-450 after reduction with dithionite and addition of CO was not observed in the region of 450nm. Moreover, metyrapone and 2, 6-dichloroindophenol did not affect this enzyme activity, but sodium azide, sodium cyanide, cupric sulfate, cadmium chloride, ${\alpha}$, ${\alpha}'-dipyridyl$, and o-phenanthroline reduced p-hydroxylase activity considerably. S. fradiae NRRL 2702 was shown to have strong p-hydroxylation activity in intact cells. This activity disappeared in its cell free extracts. In its 100,000xg supernatant, however, characteristic absorption peak of cytochrome P-450 after reduction with dithionite and addition of CO was observed at 446nm. Thus, the results herein presented suggest that acetanilide p-hydroxylase of Streptomyces aureofaciens is not related to cytochrome P-450 and may include non-heme iron protein for its activity. However, it is not clear whether acetanilide p-hydroxylase in S. fradiae belongs to the same category of S. aureofaciens.

Ginger (Zingiber officinale Roscoe) is traditionally used as appetite enhancer, improver of the digestive system, antithusive, anti-cold, antipyretic, analgesic, and antiinflammation. In vitro evaluation using human lymphocyte cultures showed almost similar indication with those in in vivo mouse study, NK cell lysing activity was improved significantly. Proliferation activity of B and T cells, and CD3$^{＋}$ and CD3$^{＋}$CD4$^{＋}$T cell subset were better observed using oleoresin or gingerol and shogaol fractions. Although there were higher activities in gingerol, the improvement was almost equal to that by oleoresin. Shogaol did not show better improvement except at higher concentration. It could be concluded that treatment with single bioactive compound, such as gingerol, did not show significant effects compared to oleoresin, the crude extract. In human study, involving healthy male adult, the improvement of NK cell lysing activity was again demonstrated and even more apparent. The mechanism involved in the protection seemed to be through the antioxidant activity of gingerol. However, other mechanism underlying the improvement of NK cell lysing activity must be involved since this improvement seemed to be specifically toward NK cell activity. Since NK cells ave specific for the elimination of virus-infected cell and mutated cells, this positive effect on the immune system are very interesting. This work has also scientifically proved that the traditional beliefs that ginger had preventive effects on common cold appeared to be reasonable.

Eighteen methanol extracts of herb-medicine used for malarial and antipyretic therapies in Korea were assessed for their antimalarial activities. Eighteen extracts showed evident antimalarial activity with $EC_50$ values ranged from $2.8\;to\;110mg/m{\ell}$. Evodia fructus showed the antimalarial activity of $EC_50\;=\;4.1\;mg/m{\ell}$ and higher selective toxicity(>8) with no cytotocixity for mammalian cells. This indicated that Evodia fructus is potent for a new effective and safe antimalarial agent. The methanol extract of Physalli radix had also strongest antiplasmodial activity with $EC_50$ value of $2.8{\mu}g/m{\ell}$.

Although tongcao has been reported to have anti-oxidative, anti-inflammatory and antipyretic effects, there is no report of the chemopreventive effect of tongcao in cancer cells. In the present study, we investigated the anti-proliferative activity of methanol extract of tongcao (MET) and its molecular target in HEp-2 human cervical cancer cells using MTS assay, western blot analysis, and DAPI staining. MET significantly decreases cell viability and induces apoptotic cell death. It affects Bid protein to be truncated resulting in the release of cytochrome c from mitochondria to cytosol whereas it did not affect other Bcl-2 family members. Thus, we clearly suggest that tongcao can be a potential naturally occurring plants having chemopreventive activity in cervical cancer.

Helminthostachys zeylanica is a rare plant grows in lightly shaded areas. The fern was traditionally used as antipyretic and antiphlogistic agents. This study was aimed to evaluate the antibacterial potential of H. zeylanica on foodborne Bacillus cereus. The chemical composition of its ethanolic extract was also determined. The plant samples were collected at Kampung Kebun Relong, Kedah, Malaysia. The ethanolic extract showed significant inhibitory activity on B. cereus with a sizeable clear zone detected on disc diffusion assay. On broth microdilution assay, the MIC of the extract on B. cereus was 6.25 mg/ml and the MBC was 12.5 mg/ml. The inhibitory activity of the extract on B. cereus was bactericidal. In the growth dynamic study, the antibacterial efficacy of the extract was concentration dependent, where a lower colony forming unit count was obtained with increased extract concentration. The SEM micrograph of extract treated B. cereus cells showed invaginations of cell wall. The bacterial cell structure collapsed after 24 h exposure to the extract. The GCMS analysis of the extract showed that the major constituents of the extract were phenol (36.26%) and quercetin (29.70%). This study is important as it shows the potential use of H. zeylanica as an effective agent to control B. cereus related infections.
