那活体上直接做的（就是说不是细胞水平的），意义大吗。
看这片文献http://www.sciencemag.org/cgi/data/309/5743/2033/DC1/1
Electrophysiology. Tc1 and wild-type littermate mice, aged 4-8 months, were
anaesthetized with an intraperitoneal injection of urethane (1.8 g/kg). LTP
was investigated in the dentate gyrus using a concentric bipolar stimulating
electrode positioned in the perforant path (AP-level with Lamda, ML-3 mm

options symbolgen;
然后用带参数的宏
%macro ICD9_Charl(LIB,CLMIN,CLMOUT);
%let DC1=%str('410','412');
.....
同一段SAS在同事的机器上就能运行而我的不行，都是用的一个平台SAS enterprise 5.
1，难道我的SAS里面哪里没设置对不能解释这个宏？
错误语句是：
%macro ICD9_Charl(LIB,CLMIN,CLMOUT) is not in a proper order.
但是在他那里就有这个：

发帖数: 1160 | 18 你们是中午聚会啊，那可能我行程上不行了，我19号晚上7:40的飞机才到，想着你们要
是晚上聚会，可以先吃，我赶过去打个招呼。我从DCA下飞机，住Arlington, 和你们聚
会的地方近么？
我20号5：00pm完事儿，晚上8:15 pm从DCA飞，只要能赶上飞机，20号也可以。
原则是不要太打搅你们的计划，有小孩儿的，可能不能待这么晚。
我估计以后每年都得飞DC1-2次，所以以后也能找机会。 |

has the Bostitch Factory-Reconditioned 3-Tool Finish & Trim Compressor
Combo Kit for $179.99 with free shipping.
I bought this kit 7 or 8 months ago, and have been quite pleased with it.
The compressor is the lightest pancake I've ever used, and it's great for
throwing in the truck to take on jobs. It replaced a porter cable and has
been reliable so far.
All three guns work well. You get a brad gun, |

Zumba Fitness is on sale for the Kinect for $25.96
Zumba Fitness is actually a great exercise game on all the platforms. I'd
say the Kinect version is definitely the best one. The reason it got bad
reviews is because people were expecting Dance Central. Zumba is more like
Just Dance where you just move and scoring is not important. If you want
precise scoring and leaderboards, Zumba Fitness is not for you. If you want

发帖数: 60932 | 21 Dance Central 2 seems to be mis-priced on the Ultimate Rewards website. It
shows regular price of 2800 pts = 2100 pts (with 25% discount).
DC1 shows regular price of 5100 = 3825pts (25%). Looks like they got them
swapped.
2100 pts is roughly $21, cheapest I've seen myself.
