â Blood viscosity â Total blood vessel length â Blood vessel diameter Resistance â¢ Factors that remain relatively constant: â Blood viscosity â¢ The stickiness of blood due to formed elements and plasma proteins â¢ Increased viscosity = increased resistance â Blood vessel length â¢ Longer vessel = greater resistance encountered
Jasmonic acid (JA) is derived from the fatty acid linolenic acid. It is a member of the jasmonate class of plant hormones. It is biosynthesized from linolenic acid by the octadecanoid pathway.
Betahistine dihydrochloride tablets are used to treat vertigo (giddiness), tinnitus (noises in the ear) and hearing loss, when these are associated with MeniereâmÃ¨niÃ©re s. Syndrome the drug helps to reduce the severity of the nausea and vertigo attacks that go with this. conditionistimine is thought to be involved in the dilation of blood vessels in the body and contraction of smooth muscle. Betahistine seems to work on the smooth muscle surrounding the blood vessels of the middle ear, improving blood flow, thus reducing the pressure in the ear.
