Any way to bold certain words in data field?

I'm working on cleaning up a report and got a request to bold certain words within a data field. I have no idea where to start or what to search on to do this. For instance, I would want to bold any occurance of "History:" or "Technique:" but not bold "history". The data is coming over as plain text in one large data field. Any help would be greatly appreciated!

Thanks!We used to have a system that fed us the data in seperate fields of
History:
Technique:
Comparison:
Findings:
Conculsion:

but now we have a system that is unable to split the data elements up before feeding it into our system. We can't add any formating on the upstream system either unfortionately. Now our report looks like garbage lol. Hopefully one of you gurus will be able to help.
