To describe the pharmacokinetics, cortisol response and behavioral changes associated with administration of sub-anesthetic xylazine and ketamine prior to castration.
The administration of sub-lethal dose of ferulic acid (5 mg/kg body weight 45 days daily) restores all the serum marker enzymes to near-normal level.
Thus, the current study was designed to evaluate the effects of acute administration of sub-anesthetic doses of ketamine, an NMDA receptor antagonist, as well as NBQX, an AMPA/kainate receptor antagonist on alcohol intake and its possible behavioural consequences.
In East and Southeast Asia, antimicrobial drugs are used extensively in the livestock and aquaculture sectors to treat or prevent infections, and they are used non-therapeutically as growth promoters, which requires the prolonged administration of sub-therapeutic doses.
129, 130 However, the exclusion of non-dermatophyte pathogens in one study and the administration of sub-clinical griseofulvin doses in both studies likely resulted in an overestimate of terbinafine's superiority.
As shown in Figure 1B and Additional file 3: Figure S1, administration of sub-cytotoxic (0.05, 0.1 and 0.2 mM) MJ did not attenuate the cell viabilities or proliferation.
Additionally, administration of sub-cytotoxic MJ attenuated the Sp1 expression and binding to MMP-14 promoter, implying the important role of Sp1 in sub-cytotoxic MJ-induced down-regulation of MMP-14 in gastric cancer cells.
In this scenario, Phase 0 (zero) trials should allow an early evaluation in humans of pharmacokinetic and pharmacodynamic profiles of test compounds through administration of sub-pharmacological doses and for a short time period to a low number of humans.
From a therapeutic perspective, the development of modulators of MMP/TIMP activity could be used as a new class of drugs for the treatment of severe sepsis, as suggested by the beneficial effect of targeting MMPs with the administration of sub-inhibitory doses of tetracycline reported in animal models of sepsis [ 47, 48].
Western blot indicated that administration of sub-cytotoxic (0.1 and 0.2 mM) MJ resulted in a decrease in the expression of MMP-14, but not of MMP-7 or MMP-9, in cultured gastric cancer SGC-7901 and MKN-45 cells.
