IMPROVED KANGAROO GUMS A “toothpaste” developed by Hebrew University of Jerusalem scientists has been shown to save the lives of captive kangaroos that develop gum disease, lose their appetites and die of starvation. Kangaroos living in captivity all over the world are known to suffer from “lumpy jaw disease,” which results in periodontal diseases, severe gingivitis and potentially deadly abscesses. The topically applied varnish that they made can treat periodontal diseases in kangaroos – thus increasing the survival rate from gum disease to 100 percent.The quality of the captive diet and environmental stress often lead to the development of periodontal diseases in kangaroos, which have severe ramifications. Four years ago, at Gan Guru kangaroo park at Kibbutz Nir David, an outbreak of the disease led to the death of about 40% of the zoo’s kangaroos. The high mortality rate results in dwindling populations – compounding the already low reproduction rates among the kangaroos and low survival rates of baby kangaroos.Existing treatment of periodontal diseases for kangaroos requires insertion of an antibiotic under anesthesia or by force several times a day, followed by solitary confinement to prevent cross infection of other animals. This treatment only increases the pressure to which the kangaroo is subjected; it is not easy to force-feed a kangaroo (which has strong arms, legs and a tail) that weighs on average of 75 kilos. This means that many kangaroos don’t benefit from the treatment and therefore may die from the illness.The innovative varnish was developed by Prof. Michael Friedman of HU’s School of Pharmacy; Prof. Doron Steinberg of the Faculty of Dental Medicine; and Dr. Eran Lavy of the Koret School of Veterinary Medicine at the Robert H.Smith Faculty of Agriculture, Food and Environment. The treatment combines disinfectant agents embedded in a polymeric matrix, and is based on the principle of sustained release of the drug from the varnish. The attending veterinarian applies the drug on the affected areas in the kangaroo’s mouth.The researchers hypothesized that by applying a version of the medicine, (which is commonly used for treating oral diseases in humans), many kangaroos can be saved. The study, whose results were published recently in the Journal of Zoo and Wildlife Medicine, was conducted over three years at Gan Guru and at Jerusalem’s Biblical Zoo. The new treatment is good news for cats and dogs too. Most dogs aged four and above have various dental problems. Like kangaroos, dogs can have periodontal infections that lead to systemic diseases.A recent study of dozens of dogs showed that the dental varnish is also effective in treating canine dental disorders. The researchers are now examining ways to integrate food supplements into the medicine.As this oral problem is not confined to Israel, the researchers have been approached by veterinarians from other countries to use this novel application in kangaroos and other animals as well.
EXCESS SMS-ING POSES DANGERS American teens who excessively send SMS messages (hyper-texters) are at higher risk of trying alcohol and other drugs, get into a fight or have sex, according to researchers at the Case Western Reserve School of Medicine in Cleveland, Ohio. As there are plenty of young Israeli hyper-texters who send dozens or even more than 100 SMSs a day, Israeli parents and the authorities should take note.Study leader Dr. Scott Frank told UPI that his survey of a cross section of high school pupils from an urban Midwestern county indicates about a fifth of teens have such a relationship with their cellphones.They are 40% more likely to try cigarettes, two times more likely to try alcohol, 43% more likely to be binge drinkers, 41% more likely to use illicit drugs, 55% more likely to have been in a physical fight, more than three times more likely to have sex and 90% more likely to report four or more sexual partners, Frank said. One wonders how they have enough time for all this. “The startling results of this study suggest that when left unchecked, texting and other widely popular methods of staying connected can have dangerous health effects. This should be a wake-up call for parents.”The study also finds that teen hypernetworking – spending more than three hours per school day on social networking sites – was linked to higher stress, depression, suicide, substance abuse, fighting, poor sleep, poor classwork, TV watching and parental permissiveness.
