    Notes: Abstract To determine how and when the satellite cells are stimulated to replicate in muscle regeneration, the rat soleus muscle was examined chronologically after bupivacaine-induced myonecrosis. Bromodeoxyuridine and desmin-positive mononuclear cells, indicating the start of satellite cell replication, were seen 25 h after bupivacaine treatment when macrophages had already invaded the sarcoplasm of necrotic fiber. These findings suggest that muscle regeneration starts as early as the time at which macrophages begin to scavenge necrotic material. Proliferating myoblasts increased in number, reaching a maximum at 49 h after myonecrosis, and decreased in number 3 days after the myoblasts fused with each other to form myotubes. The satellite cell proliferation after bupivacaine-induced myonecrosis began at almost the same time as in crush injury, and earlier than after muscle transplantation using whole intact or minced muscle fragments. The earlier begining and more rapid regenerating process probably resulted from the preservation of intact satellite cells, blood vessels and peripheral nerves in the bupivacaine-induced myonecrosis.

    Notes: Summary A satellite RNA (T73-satRNA) gave reduced symptom severity on tomato plants when coinoculated with an ordinary strain of cucumber mosaic virus (CMVO). cDNA for T73-satRNA was introduced into a binary vector (pTOK162) through a homologous recombination in an Agrobacterium tumefaciens cell, and then transferred to leaf disks of tomato. Stable integration and transcription of the cDNA in the regenerants were verified by Southern and northern blot hybridizations, respectively. Upon inoculation with CMV-O, the transformants exhibited very slight symptoms of CMV, grew normally, and finally set fruits, whereas untransformed wildtype tomato plants showed very severe symptoms, and their growth was retarded and formed few fruits. Agarose gel electrophoresis of total RNA from CMV-O-inoculated transformants detected RNA molecules corresponding to T73-satRNA.

    Notes: Abstract High spin states in the isotopes105,103In have been studied by in-beamγ-ray techniques. The reaction51V(58Ni, 2p 2n) populated those states in105In. A measurement of the linear polarizations ofγ-rays has revealed a negative-parity band in105In. The reaction48Ti(58Ni,p 2n) produced the isotope103In, which has showed an yrast spectrum similar to that observed in105In. The lifetimes of the 19/2+ and 17/2+ states in107,105In have been measured by the recoil distance method;T 1/2(19/2+)=27±4 ps andT 1/2(17/2+)=1.1 −0.3 +0.6 ns for107In,T 1/2(19/2+)=4±2 ps andT 1/2(17/2+)=0.33±0.10 ns for105In.
