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.
Worse, these and other side effects occur to some degree in up to one in 25 patients treated with medicinal doses of quinine. Happily, the low dose of quinine found in a glass or two of tonic water isn't enough to trigger these issues in most people. However, for the unlucky few, even the small amount of quinine in tonic water can cause thrombocytopenia (doctors call this rare occurrence a gin and tonic purpura).
