1. We have investigated the characteristics of the alpha9 acetylcholine receptor (alpha9AChR) expressed in hair cell precursors in an immortalized cell line UB/OC-2 developed from the organ of Corti of the transgenic H-2Kb-tsA58 mouse (the Immortomouse) using both calcium imaging and whole-cell recording. 2. Ratiometric measurements of fura-2 fluorescence revealed an increase of intracellular calcium concentration in cells when challenged with 10 microM ACh. The calcium increase was seen in 66 % of the cells grown at 39 degrees C in differentiated conditions. A sm aller fraction (34%) of cells grown at 33 degrees C in proliferative con ditions responded. 3. Caffeine (10mM) elevated cell calcium. In the ab sence of caffeine, the majority of imaged cells responded only once to A Ch presentations. Pretreatment with caffeine ingibited all calcium respo nses to ACh. 4. In whole-cell tight-seal recordings 10 microM ACh activa ted inward current was dependent on the extracellular calcium concentrat ion with an estimated PCa/PNa of 80 for the alpha9 receptor at physiological calcium levels. 5 . The data indicate that ACh activates a calcium-permeable channel alpha 9AChR in UB/OC-2 cells and that the channel has a significantly higher c alcium permeability than other AChRs. The results indicate that the alp ha9AChR may be able to elevate intracellular calcium levels in hair cell s both directly and via store release.

We studied the role of extracellular and intracellular Ca2+ in human detrusor smooth muscle contraction. Simultaneous recordings of mechanical and intracellular electrical activity were made in three different Ca2+ concentrations: normal Krebs' solution (100%), 10% of the standard Ca2+ concentration and a solution in which Ca2+ was omitted from the medium (0%). Spontaneous contractions and KCl or CCh induced contractions were studied. Ryanodine and caffeine were used to manipulate the intracellular Ca2+ stores. The present results show that only a very small amount of Ca2+ in the extracellular space is sufficient to support spontaneous and induced contractions. Spike-shaped potentials and long lasting depolarisations were recorded in all three solutions. However, the prevalence of long lasting depolarisations increased when the extracellular Ca2+ concentration was reduced. The amplitude of the spike-shaped potentials and long lasting depolarisations appeared to be negatively affected by diminishing the extracellular Ca2+ concentration. Additionally, the duration of the long lasting depolarisations was reduced in 0% Ca2+. The contraction upon KCl stimulation was primarily depending on the extracellular Ca2+. Upon muscarinic receptor stimulation, a combined activation of Ca2+ mobilisation from intracellular and extracellular stores may occur; the ratio of contribution of these two sources changes in accordance with the requirements of the conditions.

AIMS MPTP, a neurotoxin which induces parkinsonism is partially metabolized by the enzyme CYP1A2. Smoking appears to protect against Parkinson's disease (PD) and cigarette smoke induces CYP1A2 activity. Thus, we investigated the hypothesis that idiopathic PD is associated with lower CYP1A2 activity using caffeine as a probe compound. METHODS CYP1A2 activity was assessed using saliva paraxanthine (PX) to caffeine (CA) ratios. Caffeine half-life was also estimated from salivary concentrations of caffeine at 2 and 5 h post dose. 117 treated and 40 untreated patients with PD and 105 healthy control subjects were studied. RESULTS PX/CA ratios were 0. 57, 0.93 and 0.77 in treated patients, untreated patients and healthy control subjects, respectively, with no significant differences between study groups (95% CI: treated patients vs controls -0.24, 0.57; untreated patients vs controls -0.75, 0.35). However, patients with PD (treated or untreated) had caffeine half-lives shorter than that in controls (treated patients: 262 min, untreated patients: 244 min, controls: 345 min; 95% CI: controls vs treated patients 23, 143 (P = 0.003); controls vs untreated patients 19, 184 (P = 0.011)). Amongst the patients with PD, caffeine half-life was also inversely related to the age of onset of disease (P = 0.012); gender and concomitant drugs did not influence this significantly. CONCLUSIONS: Based on PX/CA ratio, there was no evidence of decreased CYP1A2 activity in patients compared with control subjects. The observed decrease in the elimination half-life of caffeine in PD may be caused by increased CYP2E1 activity, an enzyme that also contributes to the metabolism of caffeine. The latter warrants further investigation.

The average human scalp is covered by approximatey 100,000 hair follicles. Each hair undergoes hair cycle and normally 50-100 hairs randomly fall out a day, which is unnoticeable because lost hair is replaced by as many new hairs springing up daily. Hair loss results from the fall out of hair from the hair follicle. Alopecia or excessive, premature hair loss is the condition caused by many factors. Loss of hair itself does not pose critical health problems because biological role of human hair is relatively marginal. Hair on our scalp protects the head from mechanical shock, heat loss, and exposure to UV-light. The eyelashes and eyebrowes protect the eyes, and hair in the ear canal or the nasal passages help filter out particles and pathogens, thus protecting our internal organs. However, hair does play important social role: it is one of the major determinants of our appearance and identity in daily life. Fullness of hair also implicates or manifests physical integrity and youthfulness of the person. Losing hair could have more than just emotional impacts on individuals. The hair is a unique organ that goes through a characteristic cycle consisting of an immature phase, a growing phase called anagen, a transitional phase between the growing phase and the resting phase called catagen, and finally a resting phase called telogen in which the hair stops growing, waiting to fall out. 85-90% of hairs on our body are in anagen phase or growing phase, which lasts anywhere from two to five years. This phase is followed by a short regression phase, or catagen, which lasts 2-3 weeks. Approximately 1% of hair follicles are in catagen. Approximately 10-15% of hair follicles are in the resting phase, the telogen, which lasts about 3-5 months. Hair follicles typically goes through 10-20 asynchronous cycles during the lifetime. Persistent loss of more than 150 hairs would consist a state of hair loss, or alopecia, albeit it could be temporary.
