An analytical solution to the three-dimensional telegraph equation is presented. This equation has recently received some attention but so far the treatment has been one-dimensional. By using the structural similarity to the Klein-Gordon equation, the telegraph equation can be solved in closed form. Illustrative examples are used to discuss the qualitative differences from the diffusion solution. A comparison with a numerical test-particle simulation reveals that some features of an intensity profile can be better explained using the telegraph approach.

Objective: Pittosporum angustifolium Lodd. is used to treat a variety of pathogenic diseases and inflamma-tion by Australian aborigines. Practitioners of complementary medicine frequently use herbal medicines concurrently with conventional antibiotics. There is a need to evaluate their effects in combination. Methods: The bacterial growth inhibitory activity of P. angustifolium leaf extracts was assessed against a panel of pathogenic triggers of some autoimmune diseases by standard disc diffusion and liquid dilution minimum inhibitory concentration (MIC) methods. Combinational effects between the extracts and con-ventional antimicrobials were classified using the sum of the fractional inhibitory concentration. Synergistic interactions were further assessed across a range of ratios by isobologram analysis. The tox-icity of the individual samples and combinations was evaluated by Anemia lethality and 3-(4,5-dimethyl thiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium) human dermal fibroblast cell viability assays. Results: P. angustifolium leaf extracts strongly inhibited the growth of several bacterial triggers of autoim-mune diseases. The methanolic, aqueous and ethyl acetate extracts were pwrticularly good inhibitors of Proteus mirabilis and Klebsiella pneumonia growth (MIC=26 and 57 ng/mL respectively). Some combinations of the extracts and conventional antibiotics signiflcantlv potentiated the combined inhibitory activity compared to the individual components. Of the 250 combinations studied, approximately 0.02% showed synergistic interactions, 49.6% were additive, 46.8% showed indifferent interactions and antago-nism occurred in only 0.02% of the combinations. Interestingly, all of the synergistic and antagonistic combinations contained tetracycline as their antibiotic component. Conclusion: P. angustifolium leaf extracts inhibit the growth of pathogenic triggers of some autoimmune diseases. Some extracts also potentiated the activity of co

Dear editor,Human exposure to hydrocarbons(HCs)is unavoidable given their wide usage in a variety of common *** chloride(EC),a type of halogenated HC,has been used in the production of pharmaceuticals,dyes,and other chemicals used for industrial purposes.[1,2]EC was used as an anesthetic induction agent in the early 1900s.[3]Although its use as an inhalational agent has fallen out of favour,EC is still used as a topical pain medication today.[4]
