Effect of Zingiber Officinale on paracetamol-induced genotoxicity in male rats
The mutagenic effects of paracetamol (acetaminophen) in male rat using in vivomutagenicity tests, chromosomal aberrations of somatic and germ cells, molecular assay and biochemical were studied. Paracetamol genotoxicity on normal divided cells has been reported. The data obtained showed that the ability of paracetamol to bind and interact with genetic material lead to changes in chromosomal behavior and structure...

Longevity of Safed Musli (Chlorophytum borivilianum) tubers under different storage temperatures and concentrations of paclobutrazol
The effects of temperature and paclobutrazol (PBZ) in inhibiting tuber sprouting of Safed Musli during storage were determined. Tubers were stored at 28 and 10°C, each was sprayed with 0, 100, 200 and 300 mg/L PBZ weekly for 8 months. An uncontrolled precocious sprouting with excessive sprout growth of tubers was observed at 28°C without application of PBZ, while those treated with PBZ at 28°C had lesser...
