Positron emission tomography (PET) with [(11)C]raclopride has been used to investigate the density (B(max)) and affinity (K(d)) of dopamine D(2) receptors related to several neurological and psychiatric disorders. However, in assessing the B(max) and K(d), multiple PET scans are necessary under variable specific activities of administered [(11)C]raclopride, resulting in a long study period and ...

BACKGROUND Unsafe injection practices are common in developing nations. Such practices, through contaminated needles and syringes, place injection recipient, healthcare workers and the community at large at risk of infection with blood borne viruses. AIM An attempt was made to briefly describe an acute hepatitis outbreak that occurred in Gujarat, India, due to unsafe injection practices with ...

The aim of this prospective study was to evaluate the feasibility of periareolar injection of the contrast agent Sonazoid (SNZ) followed by ultrasonography (US) for the identification of sentinel lymph node (SLN) in breast cancer patients with clinically negative node. Patients (n = 100) with T1-2N0M0 breast cancer received a periareolar injection of SNZ followed by US to identify contrast-enha...

PROBLEM An effective, single-injection, multi-year, GnRH contraceptive agent is needed to control reproduction in overabundant white-tailed deer populations. METHOD OF STUDY Two GnRH conjugates, GonaCon (GnRH-KLH) and GonaCon-B (GnRH-blue protein), were prepared in emulsion form as one-injection and two-injection immunocontraceptive vaccine formulations. In addition, the GnRH-KLH protein conj...

Three series of trials involving 10 domestic short-haired cats were carried out to determine the influence of dosage of contrast media or type of chemical restraint on feline excretory urography. The 1st series (group A) involved 5 cats sedated with 2.0 mg/kg intramuscular (i.m) injection of 2% xylazine and receiving 800 mg/kg of 76 % meglumine diatrizoate (urografin). The 2nd series (group B) ...

PURPOSE To investigate the effect of subconjunctival injection of liposome-bound, low-molecular-weight heparin (LMWH) on the absorption rate of subconjunctival hemorrhages. METHODS Subconjunctival hemorrhages were induced in both eyes of 30 rabbits by the subconjunctival injection of 0.1 mL of autologous blood from auricular marginal veins. After 8 hours, randomized subconjunctival injections...

BACKGROUND Propofol is the most commonly using intravenous hypnotic for the induction and maintenance of general anesthesia. However, pain on propofol injection is a well known adverse event. Currently, acute and chronic pain can be controlled by utilizing the "gate control" theory. METHODS Patients were randomized to receive lidocaine (0.5 mg/kg; Group L), touch on IV injection site (Group T...

In this study we determined the effect of insulin injection and /or short fasting on the induction of pregnancy toxemia in Zariabi goats. Eighteen twin-bearing Zaraibi goats (around 130 days of gestation) were divided into control group (Group C, n = 6) fed ad labtium, feed deprived only group (Group A, n = 6) and feed deprived with insulin injection group (Group B, n = 6). Clinical signs of pr...

T cell-dependent immune responses generate long-lived plasma cells and memory B cells, both of which express hypermutated Ab genes. The relationship between these cell types is not entirely understood. Both appear to emanate from the germinal center reaction, but it is unclear whether memory cells evolve while obligatorily generating plasma cells by siblings under all circumstances. In the expe...
