1 Germ cells have only half the number of chromosomes as a diploid cell one of each pair. 2  The number of chromosomes is reduced from 46 (23 pairs) to 23 during the process of meiosis. 3  Because they have only half the total chromosomes in a somatic cell, they are termed haploid (n) .II. Meiosis reduces chromosome number from diploid (2n) to haploid (n) 1 diploid cell (2n) cell becomes 4 haploid (n) germ cells (eggs or sperm). During meiosis, chromosomes are replicated once in S phase (just like mitosis) into sister chromatids, but the cell divides twice.
Quinine poisoning presents a unique toxicological syndrome comprising cardiovascular quinidine-like effects, visual loss, CNS signs and cinchonism (tinnitus, paraesthesiae, ataxia).n patients with unconsciousness and ECG changes the diagnosis of quinine poisoning is suggested by fixed dilated pupils (see also differential diagnosis of coma, seizures and arrhythmias). Includes maintenance of the airway and ventilation, IV access and fluids.
The first drug found to be effective in the prevention and treatment of MALARIA. Quinine was originally derived from the bark of the cinchona tree. It is still used to treat CHLOROQUINE-resistant malaria but is no longer used as a PROPHYLACTIC. The drug is on the WHO official list. an antimalarial DRUG, extracted from the bark of the Cinchona tree. It is an ALKALOID and is effective against SPOROZOITES in the RED BLOOD CELLS. One of the first treatments for malaria, quinine is a natural product made from the bark of the Cinchona tree. It was popular until being superseded by the development of chloroquine in the 1940s. In the wake of widespread chloroquine resistance, however, it has become popular again.
