Antiviral activities of Cholistani plants against common poultry viruses.

Herbal medicines are becoming more popular and acceptable day by day due to their effectiveness, limited side effects, and cost-effectiveness. Cholistani plants are reported as a rich source of antibacterial, antifungal, antiprotozoal, antioxidant, and anticancer agents. The current study has evaluated antiviral potential of selected Cholistani plants. The whole plants were collected, ground and used in extract formation with n-hexane, ethyl acetate and n-butanol. All the extracts were concentrated by using a rotary evaporator and concentrate was finally dissolved in an appropriate vol of the same solvent. All of the extracts were tested for their antiviral potential by using 9-11 days old chick embryonated eggs. Each extract was tested against the Avian Influenza virus H9N2 strain (AIV), New Castle Disease virus Lasoota strain (NDV), Infectious bronchitis virus (IBV) and an Infectious bursal disease virus (IBDV). Hemagglutination test (HA) and Indirect Hemagglutination (IHA) tests were performed for different viruses. The overall order of the antiviral potential of Cholistani plants against viruses was NDV>IBV>IBDV>AIV. In terms of antiviral activity from extracts, the order of activity was n-butanol>ethyl acetate>n-hexane. The medicinal plants Achyranthes aspera, Neuroda procumbens, Panicum antidotale, Ochthochloa compressa and Suaeda fruticose were very effective against all four poultry viruses through their extracts. The low IC50 values of these extracts confirm the high antiviral potential against these viruses. It is worth to mention that Achyranthes aspera was found positive against IBDV through all its extracts which overcome the problem of unavailability of any known drug against IBDV. In short, the study proved that Cholistani plants are rich source of antiviral agent and their extracts can be used as good source of antiviral drugs both in crude and in purified form.

Pulmonary hypoplasia with hepatic and renal anomalies in a dead fetus.

Pulmonary hypoplasia is a developmental malformation characterized by incomplete development of lung tissue. During routine fetal autopsy of an apparently normal female dead fetus of 36 weeks gestation presented completely hypoplastic left lung, partially hypoplastic right lung, right-sided shift of heart, right-sided shift of trachea, left-sided diaphragmatic hernia through which an extra lobe from left lobe of liver extended into the left half of thoracic cavity. Left kidney was iliac in position.

Well-differentiated inflammatory liposarcoma presenting as pyrexia of unknown origin.

Liposarcomas have diverse histological appearance and clinical manifestations. Well-differentiated inflammatory liposarcoma is an uncommon sub-type, which often causes diagnostic difficulty. We report here a young female patient who presented with prolonged pyrexia and sub-diaphragmatic mass and was detected to have this uncommon soft tissue sarcoma on laparotomy.

Melanotic neuroectodermal tumour of infancy: a case report.

Melanotic Neuroectodermal Tumour of Infancy is a rare tumour. Prompt recognition of such a case is essential for the Pediatric Dentist Presented here is a case of a four and a half month old child who reported in the dental out patient department of Guru Teg Bahadur Hospital with a swelling in the right anterior maxillary ridge region.

Survey on health status of heavy vehicle drivers in Klang valley.

A survey was carried out using a medical examination format that was prepared by the Malaysian Medical Association. The findings of the survey show that of the 266 cases surveyed, 64 drivers (24% of cases surveyed) are either totally unfit to drive or temporarily unfit to drive heavy goods and passenger vehicles. This is clear indication that the current format that is being used by the Road Transport Department is inadequate and needs to be reviewed. It must also be stressed that all the above 64 drivers have been certified fit using the existing Road Transport Department format and are currently driving in our highways and roads. Heavy vehicle goods and passenger vehicle drivers if not properly examined and medically certified are not only be endangering their own lives but also that of others. It is therefore recommended that based on the data available from this survey, the Road Transport Department should seriously consider adopting the medical examination format that was formalised by the Malaysian Medical Association and used in this survey.

Process optimization for continuous ethanol fermentation by alginate-immobilized cells of Saccharomyces cerevisiae HAU-1.

Continuous ethanol production by immobilized cells of Saccharomyces cerevisiae HAU-1 has been studied using synthetic and molasses based medium in column reactors. Immobilization of 30% yeast cells biomass (wet) in 1.5% calcium alginate gel resulted in the production of 20.8 g. l-1.h-1 alcohol at a dilution rate of 0.36 h-1 with approximately 1/3rd volume of the column reactor packed with gel beads. Optimum diameter of the beads was found to be 3.5 mm for efficient fermentation. The size of the column reactor (length to diameter ratio) also affected the productivity and fermentation efficiency due to gas hold-up and mass transfer effects. Molasses could also be fermented by this system but at a lower fermentation efficiency which could be improved, to some extent, by supplementation with nutrients.

Agnihotra in the treatment of alcoholism.

Agnihotra is a Vedic ritual of litting fire in a copper pyramid pot with use of Mantras at sunrise and sunset time. It is found to have neurophysiological effect on human body and brain. Clinically it produces mental tranquility and reported to have useful adjunct effect on deaddiction. In our present study effect of Agnihotra was studied on 18 cases of alcoholism. It is found that it leads to total abstinence without other restrain after 2 weeks of continuous Agnihotra practice. An obsessive compliance to perform Agnihotra develops. After discontinuing, its effect last for another few weeks. Though relapse may develop on discontinuing Agnihotra, a sizeable number of cases i.e. 55%, continued to remain abstinent for more than 8 weeks. Agnihotra is not a total cure for alcoholism, but it may serve as an useful adjunct.

Chemosensory responses of cowpea weevil,Callosobruchus chinensis to an aquatic weed, water hyacinth,Eichhornia crassipes (Mart) Solms.

The behavioral responses of cowpea weevil,Callosobruchus chinensis to the leaf extracts of the aquatic weed, water hyacinth,Eichhornia crassipes (Mart) Solms. was evaluated by three different methods. The petroleum ether-soluble fraction ofE. crassipes induced high weevil attraction in all methods employed. The olfactometer assay provided a reading on weevil chemosensory responses, whereas the free-choice tests measured response and preference of weevils to the untreated or extract-treated food grain of their choice over a longer period. The extracts were also presented under no choice test conditions to assay them for the presence of oviposition stimulants. In all these methods the extracts of water hyacinth evoked a quick directional response. Another interesting feature is that the extract, besides producing attraction, also caused mortality of the insects.
