Then purchase famvir amex antiviral treatment and cancer control, the isolated phytocostituents were screened for antibacterial activity by employing agar disk diffusion technique utilizing some pathogenic bacteria such as Staphylococcus aureus buy discount famvir on line hiv infection ways, Escherichia coli and Bacillus subtilis order famvir amex antiviral vitamins supplements. The main aim of this research was to study the chemical and bioactivity on various kinds of Kyauk-thway samples (including natural kyauk-thway and synthetic kyauk-thway) to improve the production of Myanmar indigenous medicines. In the present research, kyauk-thway samples were collected from local area, local market, prepared from iron are (hematite) and iron salt (ferric sulphate). The citric acid contents from these samples were analysed by cation exchange method. It was found that amount of haemogolbin was increased in mice blood during one month. By considering all the above facts, the production of Myanmar indigenous medicines may be improved. Thus this research will be of much benefit in the production of high quality indigenous medicines in Myanmar. A natural iron rich compound, Kyauk-thway which is being used by local people for the treatment of anaemia was scientifically investigated. Iron contents of threes types of samples named as Kyauk-thway collected from different sources were determined by atomic absorption spectrophotometer. One of them, specified as ferric ammonium citrate which is easily available in market showed maximum content of iron (27. Where acute toxicity of this market, sample was studied, it was observed 100% death at the maximum dose of 6mg/kg. Kyauk-thway has revealed to contribute for systematic use of it in replacement or supplemental therapy. Oral rehydration honey salts developed by Department of Traditional Medicine, Ministry of Health, replacing glucose with honey was investigated for its chemical aspects, comparing with standard oral rehydration salts. Three physico-chemical test parameters pH, electrolytes and total reducing sugar contents were tested. Results obtained were discussed and recommandation proposed for therapeutic effectiveness of oral rehydration honey mixture preparation. The aminoacids present in the acid hydrolysate were identified by the 2 dimensional paper chromatographic techniques. Rehydration measure should be instituted as early as possible when life threatening dehydration state due to diarrhoea or severe fever is suspected or detected. Home- based fluids are usually given under such circumstance and thus chemical compositions of syrups (n=9), soft drinks (n=5), fresh fruit juices (n=3) and plant decoctions (n=7) were analysed by using published methods and atomic absorption spectrophotometer. The local name Thin-baw-mahnyo possesses two different species of genus Catharanthus. The botanical name Catharanthus roseus was noted for Thin-baw-mahnyo (ahni) and Catharanthus alba for Thin-baw-mahnyo (ahpyu). The plants are cultivated for ornamental flowers as well as for indigenous medicinal purposes. Physicochemical characterization of the dried leaves owder was conducted using the standard analytical procedure described in physicochemical standard of Unani medicine and Myanmar Traditional Medicine Formulary. A triterpenoid compounds, ursolic acid was isolated and identified from ethanolic extract of dried leaves powder. Moreover, the quantity of total alkaloids in dried leaves powder was determined and observed to be 1. The main aim of this research work is to study some biological activities of Ipomoea batatas (L. The antimicrobial activity of various crude extracts of leaves powder and stem of Ipomoea batatas (L. From above data, crude extracts of leaves showed more significant zone of inhibition than those of stem.

Once the margins of the mass are clearly identified, a slightly thicker metal spatula may be used to finish the dissection. Fragments may fall caudally into the nasal cavity and must be flushed from their resting place behind the turbinates. Once the rhinolith is removed, the lining of the nasal cavity should be swabbed and evaluated cytologically and by culture for mycotic and bacterial pathogens. The nares should be flushed with dilute chlor- hexidine, and any fungal or bacterial component should be treated systemically with appropriate an- timicrobial medications. Infraorbital Sinusitis Infraorbital sinusitis in birds may lead to secondary lacrimal and conjunctival infections, chronic rhinor- rhea and other upper respiratory problems. Fre- quently, nutritional problems such as hypovitami- nosis A predispose a bird to secondary infections with bacteria, yeast and fungi. A sinus flush technique can be used to obtain samples for cytology and cultures (see Chapters 10 and 22). If untreated, mild infraorbital sinusitis may progress to abscessation that requires surgical exploration and curettage (see Color 22). Clinical signs may in- clude sneezing, rhinorrhea, swollen eye, other ocular diseases, periorbital swelling and conjunctivitis. In some cases, purulent material can be visualized be- low the conjunctiva of the eyelid or the globe itself (Figure 41. The infraorbital sinus is initially opened in the same location described for sinus flushing (see Chapter 10). This area is highly vascular, and laser, if avail- able, is best for providing hemostasis. Bipolar radio- surgical units on higher coagulation settings may also be effective. Pressure may be applied to the area with a cotton-tipped applicator to allow visualization of the vessels.
