We studied the contamination level of the acaricides Folbex VA (bromopropylate, BP), Perizin (coumaphos, CM) Apistan (fluvalinate, FV) and Bayvarol (flumethrine, FM) in brood combs, sugar feed, honey and in new beeswax. All samples were analysed by gas chromatography with ECD detection. After one normal acaricide treatment, in autumn, the brood comb wax was contaminated by all these acaraicides...

In an attempt to restrict drug absorption from suppositories to only the lower rectum, mucoadhesive lidocaine (LID) suppositories were prepared using WitepsolR H-15 as a base, and CarbopolR 934p (CP) and white beeswax (WAX) as additives. CP has a mucoadhesive property and WAX gives the suppositories stiffness. The suppositories containing 109{(, CP and 20% WAX stayed in the lower recta of rats ...

(a) Penicillin.-Most significant developments have taken place in the field of antibiotics, especially with repository penicillins. The treatment, which used to consist of injections every 2 to 4 hours with aqueous penicillins, daily with penicillin in oil-beeswax, and sometimes once or twice weekly with procaine penicillin with aluminium monostearate, may now be achieved by a single or a few i...

The control of venereal diseases in rural areas presents certain problems and difficulties not met with in the city. The County of Cornwall, with which this paper deals, has a scattered population of 322,500. No industrial areas exist, but there are some half dozen market towns and small seaports each with from ten to sixteen thousand inhabitants. Five clinics for the treatment of venereal dise...

The utility of the trachea! transplant model as a tool in in vivo carcinogenesis studies depends largely on the development of a good drug delivery system affording reproducible, sustained carcinogen release. Previously used methods have proven to be less than satisfactory. We studied the release of benzo(a)pyrene, 7,12-dimethylbenz(a)anthracene, and 12-O-tetradecanoylphorbol-13acetate from pel...

In Switzerland the acaricides Folbex VA (bromopropylate, BP), Perizin (coumaphos, CM), Apistan (fluvalinate, FV) Bayvarol (flumethrine, FM) are used for varroa control. We studied the contamination level of BP,CM and FV in brood and honey combs, sugar feed, honey after field trials. In samples of recycled pure beeswax and propolis, gathered by beekeepers we examined the level of all four acaric...
