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.
Tonic contains 83 mg. of quinine in a liter. An eight-ounce glass or tonic would only have about 20 mg of quinine, considerably less than the dose that used to be prescribed for leg cramps (200 to 300 mg).learly, quinine can be dangerous for certain people, but the FDA has not banned quinine from tonic water. Quinine gives this beverage its distinctive flavor. Either the FDA doesnât consider tonic water a danger to public health or the agency worries about arousing the ire of millions of gin and tonic drinkers.
