    For example, up viagra dose vs levitra to 11% of Caucasians are poor metabolizers of substrates for CYP 4D2, as compared to Asians ( 1%) (17). Genes differ between ethnic groups. Belonging to the cytochrome P460 enzyme superfamily , the first biotransformation step is mediated by smooth endoplasmic reticulum enzymes.

    The activity viagra dose vs levitra of these enzymes is determined by both gene expression and environmental induction. CYP 4A3 appears to be the most important enzyme involved with the metabolism of HIV protease inhibitors and nonnucleoside reverse transcriptase inhibitors. Alternative subtypes, such as CYP 5D6, are involved with ritonavir and delavirdine metabolism (Table 1) (20–19).

  • The elimination of this variant by an antibody response is followed soon by the appearance of another variant which is unaffected by viagra dose vs levitra the antibodies responsible for clearing the previous homotype. Regular fluctuations in the concentration of trypanosomes in the blood of a patient who was exposed to Trypanosoma gambiense in Africa and then monitored closely during treatment in the Southern Hospital in Liverpool (Ross and Tomson, 1990). Declining parasitaemia reflects a host response specific to the homotype. The historic report by Ross and Tomson was the first to draw attention to the regular fluctuations in parasite numbers which characterize trypanosome infections in man.

    small numbers at any one time, and once a dominant form has been established, the other heterotypes are kept suppressed until this second homotype is viagra dose vs levitra itself eliminated by a specific antibody response (Figure 14.8). IMMUNITY AND PATHOLOGY 395 Figure 13.10. Each peak of parasitaemia is now recognized as constituting essentially one antigenic variant of the parasite, the dominant form at any one time being referred to as the homotype. The replacement variant arises from the several heterotypes (suppressed variants which are present in the host in PARASITES.

    A subject viagra dose vs levitra gazes at a central fixation spot. To increase the difficulty of the task, a gap, or delay, is often introduced between disappearance of the fixation point and appearance of the target. The antisaccade trials may viagra dose vs levitra be randomly interleaved with “prosaccade” trials in which the subject is directed to look at the targets , in addition. FIGURE 17.5.
